One number is the fraction of another number, generally referring to the ratio: standard labor should be found in the production group, compared with each other and evaluated as a number.

A number that indicates that one number is a fraction of another number is called a number.

Usually used in industrial and agricultural production, indicating the increase of output. A few percent is a few tenths.

For example, this year's grain output has increased by "20%" compared with last year.

"20%" means two tenths, which means that the grain output this year has increased by 20% compared with last year.

When calculating a number, there are two numbers, A and B. Find the ratio of B and A and turn the ratio into a pure decimal. Then the pure decimal is called the number from B to A. The first digit after the decimal point is called "Cheng" or "Minute", and the second digit after the decimal point is called "Li".

For example, last year's grain output was 50,000 Jin, and this year's grain output is more than last year's 1 10,000 Jin, so the percentage of this year's grain output is 1.275 = 0.2, which means that this year's grain output is 20% more than last year's.

Mutual transformation of several numbers and other numbers

Method:

Fraction X 10= number.

Fraction/10= decimal (Fraction divided by 10 equals decimal)

Score X 10= percentage.
