Answer 2

Proportion

Step-by-step explanation:

A proportion is an equation which states that two ratios are equal.

A proportion relates two parts of an equation, these can be two ratios, an example of proportion is as follows:

`(1)/(2) =(2)/(4)`, or
`(3)/(9) =(1)/(3)`

This examples are proportions since both sides of the equation have the same value (in the first case 0.5 and in the second case 0.33..), in other words: the ratio 1:2 and 2:4 are the same, and the ratio 3:9 and 1:3 are the same.

When a ratio is known, a proportion can be found by multiplying or dividing both elements of the initial ratio by the same number.
