5:25 =5/25 (to get the same ratio multiply both numerator and denominator with the same number)

5/25 *4/4 = 20/100

5:25 = 5/25 (to get the same ratio divide the fraction with same number)

5/25*5/5 = 1/5

Thanks (I think you followed the procedure)

The simplest ratio is 1:5

Divide both sides by 5 to get this ratio.

For a moment I thought a "prosiger" was a technical term I had never heard of. I think you meant to say "procedure".

To work this out , determine the highest common factor between the 5 an 25. In this case it is 5.

Then divide what is to the left and right of the colon by the HCF which is 5

This gives the ratio as 1:5

The problem is 5:25.

To solve this problem, you would use the following procedure:

Divide each number by 5.

Thus, 5/5 = 1 and 25/5=5

Thus the answer is 1:5
