What is the relationship between the basic properties of fractions and the basic properties of decim

What is Decimal Notation? What units of counting can you name?

The rate of advance between each two adjacent counting units is 10, and 10 lower units can be advanced into a higher unit.

How do I compare the size of two numbers?

Fractions: (1) Divide into decimals or integers first, and then compare the size. (2) The first pass is divided, the denominator is the same, the larger the numerator, the larger the score.

Decimal: (1) Compare from the whole place, if the whole place is the same, look at the digit after the decimal point. (2) Multiply 10 or at the same time, turn it into an integer, and then compare the size.

What is the relationship between the basic properties of fractions and the basic properties of decimals?

Fraction: The denominator and numerator of the fraction expand or shrink by the same multiple at the same time (except for 0), and the size of the fraction remains the same.

The denominator and numerator of the fraction are multiplied or divided by the same number at the same time (except 0), and the magnitude of the fraction does not change.

Decimal: Add 0 or remove 0 at the end of the decimal number, and the size remains the same.

4. What happens to the decimal point when the decimal point moves to the decimal size?

If you move the decimal point one place to the left, the decimal will be reduced by a factor of 10, and if you move the decimal point to the right by one place, the decimal place will be expanded by a factor of 10.

5. What is the meaning of factor, multiple, prime number, and composite number?

Factor: In division, the divisor is the factor of the dividend.

Multiple: In division, the dividend is a multiple of the divisor.

Prime number: A prime number, also known as a prime number, has no other factor than 1 and itself.

Composite Number: A number has other factors besides 1 and itself.

The basic properties of fractions: the numerator and the denominator expand at the same time and the latter shrink by the same multiple, and the fractional value remains unchanged.

The basic properties of decimals: add 0 to the end of the decimals, the latter remove 0, and the size of the decimal does not change.

As for what it does, I really don't.

Summary. 1.A fractional decimal is a decimal form that represents a fraction, and it consists of a numerator, which represents the integer part of a decimal number, and a denominator, which represents the fractional part of a decimal number.

2.The value of the fractional is equal to the numerator divided by the denominator, i.e., fractional decimal = numerator denominator. 3.

The denominator of the fractional must be an integer multiple of 10, such as 30, etc. 4.Fractional decimals can be converted to fractional form, such as 1 10=1' 10, 2 20=1' 10,3 30=1' fractional decimal can be converted to decimal form, such as 1 10=, 2 20=, 3 30=.

I'm still a little confused, can you be more detailed?

A decimal is a form of denoting a fraction that separates the integer part from the decimal part and can be used to represent any fraction. The basic properties of decimals include:1

The integer part of the decimal decifies the numerator, and the decimal part denotes the denominator; 2.Both the integer part and the decimal part of a decimal can be of any length; 3.The integer part and the decimal part of a decimal number can be any number; 4.

The integer part and the decimal part of the decimal can be arbitrary; 5.The integer part and decimal part of a decimal number can be of any type, such as integer, floating-point, percentage, and so on. When using decimals, sometimes problems arise, such as insufficient precision of decimals, inconsistencies between the integer and decimal parts of decimals, etc.

The cause of these problems may be due to insufficient precision of the decimals, or inconsistencies between the integer and decimal parts of the decimals. The solution to these problems is to first determine the precision of the decimal, and then make sure that the integer part of the decimal coincides with the decimal part. If the precision of the decimal is not enough, rounding can be used to improve the accuracy; If the integer part and the decimal part of the decimal do not match, you can use scientific notation to solve it.

Personal tip: When using decimals, pay attention to the precision of decimals and the consistency of integer and decimal parts to avoid problems.

Summary. Decimals, like integers, have the basic properties of addition, subtraction, multiplication, division, and power, and can be calculated and deformed by moving and dividing decimal points.

Decimals, like integers, have the basic properties of addition, subtraction, multiplication, division, and power, and can be calculated and deformed by moving and dividing decimal points.

Fellow, I really didn't understand, I can be more specific.

Decimals are the representations of fractions in the decimal system, and it has the following properties. First, the size of the decimal is equal to the size of the fraction it represents. For example, 8 10 is represented, which is equal to 4 5 in size.

Secondly, the size of the decimal orange is related to the digits after the decimal point, and different digits represent different sizes. For example, and both denote forty-five hundredths and ninety, but they are not equal in size. Thirdly, the calculation of decimal numbers is the same as that of fractions, with four rules of operation: multiplication, division, addition and subtraction.

Finally, decimals can be converted into fractions, for example to 45 100. Decimals are a very important concept in mathematics and have a wide range of applications in practical life and learning.

Summary. The basic properties of fractional decimals include:1

Rational numbers: Fractions and decimals are both rational numbers, and they can be expressed as the ratio of two integers. Rational numbers have basic operations such as addition, subtraction, multiplication, and division.

2.Equivalence: A fraction and a decimal may look different, but the numbers they represent are equal.

For example, 5 10 and represent the same number. 3.Decimal:

Any fraction can be converted to a decimal place, and this decimal can be notated using decimal notation (i.e., a number after the decimal point). For example, 1 4 can be written as an infinite loop decimal: some fractions are infinitely looped in decimal form, e.g. 1 3 can be expressed as or .

This decimal has many special properties and laws. 5.Number of decimal places:

The number of decimal places can be extended indefinitely, but in practice, only a limited number of digits are usually retained, and it is necessary to pay attention to issues such as precision errors and rounding rules. 6.Fraction Simplification:

Dividing a fraction into its simplest form, i.e., the numerator and denominator are copolymeric, makes it easier to read and calculate, and avoids large numerical values.

Good. I'm still a little confused, can you be more detailed?

The basic properties of fractional decimals include:1Rational numbers:

Fractions and decimals are both rational numbers, and they can be expressed as the ratio of two integers. Rational numbers are accompanied by basic operations such as addition, subtraction, multiplication, and division. 2.

The basic property of fractions: the numerator and denominator of fractions are multiplied or divided by the same number at the same time (except 0), and the magnitude of the fraction does not change.

The basic property of decimals: add 0 to the end of the decimal or remove 0, and the size of the decimal remains the same.

Decimals can be converted into fractions, but fractions are not always decimals.

Therefore, the basic properties of fractions have nothing to do with the basic properties of decimals.

The nature of decimal numbers is that the size of the decimal does not change if a "0" is added to the end of the decimal or "0" is removed.

The nature of fractions is that the numerator and denominator of a fraction are multiplied or divided by the same number at the same time (except 0), and the size of the fraction does not change.

None of the values changed after they changed.

The basic properties of fractions: the numerator and the denominator expand at the same time, the latter shrinks by the same multiple, the fractional value does not change, the basic properties of the decimal number: 0 is added to the end of the decimal and the latter removes 0, and the size of the decimal does not change.

The basic property of fractions: the numerator and denominator expand or shrink the same multiple at the same time, and the fractional value remains the same.

The basic properties of decimals: add 0 to the end of the decimal or remove 0, and the size of the decimal remains the same.

Similarities: Fractions can be turned into decimals, and decimals can be turned into fractions.

The basic property of fractions: the numerator and denominator of a fraction are multiplied or divided by the same number at the same time (except zero), and the magnitude of the fraction does not change. Basic properties of decimals:

Add or remove zeros from the end of the decimals, and the decimal size remains the same. Because decimal is another way to write decimal fractions, the basic properties of decimal numbers are subordinate to the basic properties of fractions, i.e., the basic properties of decimal numbers are equivalent to the numerator and denominator of fractions multiplied or divided by the same number at the same time (this number is just ......Nothing more. When it comes to the bottom, decimal and fraction are just a subordinate relationship, and their properties have the same relationship.

What is the connection between the decimal property and the fundamental nature of fractions?

The basic properties of fractions: the numerator and the denominator expand at the same time, the latter shrinks by the same multiple, the fractional value does not change the basic properties of decimals: 0 is added to the end of the decimal, the latter removes 0, and the size of the decimal does not change, and the decimal can be regarded as the denominator is ...

, then the nature of fractions can also be used on decimals.

The basic property of fractions: the numerator and denominator of a fraction are multiplied or divided by the same number at the same time (except 0), and the magnitude of the fraction does not change.

The basic property of decimals: add or remove zeros at the end of the decimals, and the size of the decimal remains the same.

Add or remove zeros at the end of the decimals, and the decimal remains the same.

Add or remove zeros after the numerator and denominator of the fraction, and the fractional value remains the same.

The basic property of decimals is to remove zero and add zero, whereas the property of fractions is to multiply or divide.

The decimal is the denominator is 10,100 ,..The basic property of the decimal is that the decimal is not finished with a "0" or "0" is removed, and the size of the decimal remains the same.

The basic property of fractions is that the numerator and denominator of fractions expand and shrink by the same multiple at the same time, and the size of the decimal does not change.
