Answer 3

Option 1 is a proportion.

To check if two ratios are proportional, we cross-multiply and see if the product of the means equal the product of the extremes. In this case,

For Option 1:

7 x 22 = 8 x 20

154 = 160

The products of the means and extremes are equal indicating that the ratios are proportional.

For Option 2:

7 x 24 ≠ 8 x 21

168 ≠ 168

The products of the means and extremes are not equal indicating that the ratios are not proportional.
