Now, in order for it to be a proportion, both the number and the denominator must turn to the other number by the same method. I'll clarify when we do the steps.

So, the first one is 4/10 and 10/25

The first thing that you would do is divide 10 by 4, and then 25/10

When you do that, it turns out that they both equal 2.5. This means that both the number and denominator go to the new number with the same method, multiplying by 2.5

So, the answer would be A

The ratios that form proportion is expressed as 4/10 and 10/25

Proportions is a way of finding the ratio of two integers

For example, the proportion of a to b is a/b

We need to find two fractions that are the same:

For the fraction 4/10

4/10 can also be expressed as (2*2)/(2*5)

4/10 = 2/5

Similarly for the fraction 10/25;

10/25 = (2*5)/(5*5)

10/25 = 2/5

Hence the ratios that form proportion is expressed as 4/10 and 10/25
