Question

State of each pair of ratios form proportion

3) 4/3 and 16/12

4) 4/3 and 8/6

Answer 1

To determine if each pair of ratios is proportional, we can compare their cross products.

3) 4/3 and 16/12:

Cross product of the first ratio: (4)(12) = 48
Cross product of the second ratio: (3)(16) = 48

Since the cross products are equal (48 = 48), the ratios are proportional.

4) 4/3 and 8/6:

Cross product of the first ratio: (4)(6) = 24
Cross product of the second ratio: (3)(8) = 24

Since the cross products are equal (24 = 24), the ratios are proportional.
