and

proportional? Explain.

1 answer

Yes, the ratios 25/45 and 15/27 are proportional. To show this, we can use the cross-product property of proportions.

Cross-product property: a/b = c/d if and only if ad = bc

25/45 = 15/27

25 x 27 = 45 x 15

675 = 675

Therefore, the two ratios are proportional.
