What is 4 fifths and 4 fifths?

The analysis is as follows: one fifth is equal to four fifths.

Score Calculation Method:

1. Same denominator.

Fractions are added (subtracted) and the denominator remains the same, i.e. fractional units.

Unchanged, the numerators add (subtract), and the offer points that can be reduced.

Example: <>

2. The addition (subtraction) of different denominator fractions, that is, the use of the basic properties of fractions to convert different denominator fractions into fractions of the same denominator, change the unit of fractions without changing the size, and then calculate according to the addition (subtraction) method of fractions of the same denominator, and finally the offer points that can be reduced.

Example: <>

1/5 4 = 4/5

Because he says four fifths, which is four fifths multiplied, there is a fifth 4 = four fifths.

Four-fifths.

4/5 to decimal is, and its calculation steps are:

1. First understand the method of dividing fractions into decimals, that is, dividing the numerator of the fraction by the denominator.

2. In the fraction of four-fifths, the numerator is 4 and the denominator is 5, that is, 4/5 is equal to 4 divided by 5.

3. By calculating, it is calculated that 4 divided by 5 is equal, that is: 4/5 is equal to a decimal place.

Fractional decimal can be divided into three cases:

1. Fractions are reduced to finite decimals. A sufficient requirement for a simplest fraction to be reduced to a finite decimal is that the prime factors of the denominator are only 2 and 5.

2. Fractions are converted into pure cyclic decimals. A sufficient and necessary condition for a minimum fraction to be reduced to a pure cyclic decimal is that there are no 2 and 5 in the prime factor of the denominator, and the number of digits of the cyclic node is equal to the smallest 99 divisible by the denominator of the simplest fraction....The number of 9 in the form of 9.

3. Fractions are converted into mixed circulation decimals. A simple fraction is sufficiently necessary for it to be converted into a mixed cyclic decimal if the denominator contains both prime factors of 2 or 5 and prime factors other than 2 and 5.

In the formed mixed cyclic decimals, the number of non-cyclic digits is equal to the greater of the exponents of factor 2 or 5 in the denominator; The number of digits of the cyclic section is equal to the smallest 99 that can be divisible by a factor different from 2,5 in the denominator....In the form of 9, count 9.

4 in 4 and 1 in 5 compared to 1 in 4 large. Column Equation:

So 4 in 4 and 1 in 5 compared to 1 in 4 large.

Notes on scores:The denominator must not be 0 because the denominator is equivalent to the divisor. Otherwise, the equation cannot be held and the numerator can be equal to 0 because the numerator is equivalent to the dividend.

It is equivalent to 0 divided by any number, regardless of the denominator, the answer is 0.

The numerator or denominator in a fraction cannot be an irrational number (such as the square root of 2) after being reduced, otherwise it is not a fraction. The numerator and denominator of a fraction are multiplied or both divided by the same non-zero number, and the resulting fraction is equal to the magnitude of the original fraction.

1/5 4/5 = 4/25

Four-fifths of one-fifth of two-fifths of two-fifths

This problem is calculated according to the definition of a mathematical ratio:

Unknown=5x1 4=5 4=, so the result is 5 out of 5. Example.

It can be expressed as 5 4, i.e. the fraction with the numerator is 5 and the denominator is 4, or it can be written as 1 and 1 4. Zhengtong.

4 is the hundredth of 5, that is, 5 times the hundredths of a hundred oranges is equal to 4, that is, 4 divided by 5 is equal to the hundredths of the group, 4 5 eighty percent, so 4 is 80 percent of the hundredths of 5.

3 fifths of the tour Qingxian four is 12 fifths. The score of the three fifths is 12 5, (3*4 5=12 5). The unit of counting 12 5 is 1 5, and there are 12 1 5 in 12 5.
