What is the difference between a percentage and a fraction? 5

1 Meanings are different. A percentage is "a number that indicates that one number is a hundredth of another number." "It can only represent a multiple relationship between two numbers, not a specific quantity.

For example, it can be said that 1 meter is 5 meters of 20, and it cannot be said that "a length of rope is 20 meters." Therefore, the percentage cannot be followed by the name of the unit.

The fraction is "the number of such parts or parts that are divided equally into parts of unit '1'". A fraction can not only represent a multiplier relationship between two numbers.

2 The range of application is different. Percentages are often used in surveys, statistics, analysis and comparison in production, work and life. Fractions are often used in measurements and calculations when no integer results are available.

3 Different forms of writing. Percentages are usually not written as fractions, but are represented by a percent sign " ". Such as:

Forty-five percent, writing: 45; The denominator of the percentage is fixed at 100, so no matter how many common divisors there are between the numerator and denominator of the percentage, it is not divided; The numerator of the percentage can be either a natural number or a decimals. The numerator of a fraction can only be a natural number, and its representation is:

True fractions, false fractions, and band fractions, and those whose calculation results are not the simplest fractions are generally differentiated into the simplest fractions by approximation, and those that are false fractions are turned into band fractions. Any percentage can be written as a fraction with a denominator of 100, and a fraction with a denominator of 100 does not always have the meaning of a percentage.

4.Percentages cannot carry the name of the unit; When the fraction represents a specific number, the unit name can be included.

The percentage is divided by the denominator and multiplied by 100%.

For example, 1 3: is 1 divided by 3 = omitted later), multiplied by 100% = 2 5 is 40%. Got it?

What percentage is the hundredth of a number.

The fraction is what fraction of a number is.

Fractions can represent quantity + unit name, while percentages cannot

Percentages are written differently from fractions and have different meanings.

A percentage simply represents the relationship between two quantities.

A fraction represents both a relationship between two quantities and a specific quantity.

Scores andPercentagesThe difference is positive: the meaning is different, the percentage only represents the relationship between the multiple leg ratio of the two numbers, and cannot bring the name of the unit; Fractions can represent both specific numbers and the relationship between two numbers, and the unit name can be used when representing specific numbers.

A percentage indicates how many percent of a number is another number, also known as a percentage.

or percentages. Percentages are not usually written as fractions, but with the symbol "%" percentile.

to represent. A fraction is a part of a whole or, more generally, any equal number of parts, expressed as the ratio of an integer a to an integer b. A fraction indicates that a number is a fraction of another number or the ratio of an event to all events.

The unit "1" is divided into several parts, and the number of such parts or parts is called a fraction. The numerator is on top and the denominator is on the bottom.

Connection and difference between fractions and percentages:

1. The intrinsic relationship between percentages and fractions:

Both can represent the multiplier relationship between two quantities, and the percentage is a special fraction.

2. The difference between percentages and fractions:

1. The meaning is different, the percentage only represents the multiples relationship of the two numbers, and cannot contain the name of the type of the single congratulatory object; Fractions can represent both specific numbers and multiples of two numbers, and can be used with names when representing specific numbers.

2. The numerator of the percentage can be an integer or a decimal; The numerator of a fraction cannot be a decimal, but can only be a natural number other than 0; Percentages cannot be reduced, and fractions can generally be reduced to the simplest fraction by reduction.

3. Any percentage can be written as a fraction with a denominator of 100, and a fraction with a denominator of 100 does not have the meaning of a percentage.

4. The scope of application is different, percentages are often used in investigation, statistics, analysis and comparison in production and life, while fractions are often used when integer results are not obtained in calculation and measurement. Zen guess.

Percentages and fractions are mutualized:

1. Percentile fraction:

Write the percentage as a fraction whose denominator is 100, and then reduce the differentiation Jane. In addition, when the numerator of the percentage is a decimal, the numerator should be reduced to an integer first.

2. Fractional percentage:

1) Divide the numerator by the denominator, make it into a decimal, and then turn it into a percentage.

2) Multiply the numerator and denominator by a number at the same time so that the denominator is 100, and then turn the denominator into a percent sign.

Percentage: The meaning of percentage: The number that indicates that one number is a few percent of another number is called a percentage.

Percentages are also called percentages or percentages. Percentages are usually not written as fractions, but are represented by the symbol shouting percent sign (%). If it is written as 41%, 1%

Since the denominator of the percentage is 100, that is, it is all in 1% as a unit, which is easy to compare, therefore, the percentage has a very wide application in industrial and agricultural production, science and technology, and various experiments. In particular, percentages are often used in surveys, statistics, and comparisons.

Fraction: A fraction represents a fraction of a number that is another number, or the proportion of all events in an event. The unit "1" is divided into several parts, and the number of such parts or parts is called a fraction.

Same:1A fraction can represent the relationship between two numbers; It can also indicate what a quantity is. It can be a specific value on its own, or it can be a ratio compared to other values.

2.Percentage**Percent.

Different Circles Seepage Dust:

A percentage is the percentage (rate) of one number to another, and is a special fraction with a denominator of 100, which has a special meaning.

Percentages are indeed fractions, but since they are separated from fractions, they have taken on a unique meaning. It's not a score anymore, it's not a special score.

The two concepts of percentages and fractions have their similarities and different characteristics, so it is easy to get confused and not understand the difference between them when learning these two concepts. Below I have summarized from my own teaching practice that we can analyze the differences between percentages and fractions from five aspects.

1. Distinction in the sense of representation. A percentage is a number that means "a number is a percentage of another number", also known as a percentage feast or percentage, which only indicates the multiplier relationship between two quantities; The fraction is to divide the unit "1" into several equal parts, representing the number of such a part or several parts, it can not only represent the multiplier relationship between the two quantities, but also represent the specific value.

Second, there is a difference in the way it is written. Percentages are usually not written as fractions, but are written with the fractional line and denominator removed, and the percent sign "" such as 62 percent is written as 62 instead of 75 100 after the numerator.

3. Distinguish from the name of the unit. The percentage only indicates the multiplier relationship between two quantities, which is an anonymous number and does not have the name of the unit after it. The score is different, if it indicates a specific quantity, it is a number, and the name of the unit should be included; If it represents the multiplier relationship between two quantities, it is an unnamed number without a unit name.

Fourth, the difference in the form of expression. The denominator of the percentage is fixed at 100 and is represented by a percent sign, the numerator can be an integer or a decimal, which can be greater than the denominator or less than the denominator; Percentages cannot be reduced or written as fractions. Fractions are expressed in the form of true fractions, false fractions and mixed fractions, and the calculation results are generally reduced to the simplest fractions, and if they are false fractions, they are usually turned into mixed fractions.

Fifth, the difference in application. Percentages are mainly used for survey statistics, analysis and comparison; Fractions are mainly used when the results of whole numbers are not available in measurements and calculations, and can also be used for ascension or analysis and comparison.

2 in all. I'll answer with a reward.

Write with a bonus to see all 2.

Nanshan is full of birds.

Concern. First, the similarities.

1. The substance is the same.

Percentages and fractions are essentially ratios. The fraction is the ratio of an integer a to a positive integer b that is not equal to the integer.

2. All belong to scores.

A percentage is a special fraction with a denominator of 100, and its numerator may not be an integer. A percentage indicates how many percent a number is another and represents a ratio.

Second, the differences.

1. The form is different.

Percentages are not usually written as fractions, but are represented by the symbol "%" percentile.

The horizontal line in the middle of the fraction is called the fraction line, the number above the fraction line is called the numerator, and the number below the fraction line is called the denominator. Read as fractions.

2. Different types.

There are three types of fractions: true fractions, false fractions, and fractions with fractions.

The value of the true fraction is less than 1. The numerator is smaller than the denominator, and the value of the false fraction is greater than 1, or equal to 1. If the numerator is greater than 1 for fractions with a large or equal denominator, the fraction part that follows must be a true fraction.

There is only one type of percentage.

Extended information: 1. Percentages often indicate a proportional relationship, but percentages can sometimes exceed 100%.

2. The nutrient reference value in the nutrient facts table on the food packaging box does not indicate the percentage of the substance in the food, but the proportion of the amount of the substance in the food to the per capita normal daily intake, which also explains why the sum of the percentages in the nutrition facts table is often not equal to 100%.

For example, assuming that normal people should consume an average of 60 grams of fat per day, then a certain Li Qiaojiao food containing 6 grams of fat per 100 grams should be marked with 10% instead of 6% in the nutrition facts list.

3. The survival rate, germination rate, attendance rate, oil yield, score rate, etc. indicate that the percentage of individuals in the total will not exceed 100% (maximum 100%)

4. Percentages have different meanings in different situations. For example, the sentence "'The probability of precipitation tonight is 20%" indicates that there is a 20% probability of rain (snow) tonight, but it does not mean that it will rain (snow) 20% of the time tonight.
