Question

: Enter your answer and show all the steps that you use to solve this problem in the space provided.

Are the ratios
25/45
and
15/27
proportional? Explain.

Answer 1

Yes

Explanation:

If you divide 25/45 by 5 you get 5/9

Then you divide 15/27 by 3 you also get 5/9

Since both are equal to 5/9 they are proportional.

Answer 2

Yes

Explanation:

First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).

First ratio becomes (25:5)/(45:5) = 5/9

Second ratio becomes (15:3)/(27:3) = 5/9

Since we can simplify them in that way that both are the same that means they are proportional.

because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
