Question

I dd the assignment and I didn't get the right answer, the correct answer was 3/4

Can you guys help me understand where does 3/4 come from

Answer 1

Explanation:

The 2 figures are similar so corresponding sides are in the same ratio.

The factor is the value that you have to multiply a side in the first rectangle to get the corresponding side in the second rectangle.

12 ----> 9

So:

12 * f = 9 where f is the factor

f = 9/12 = 3/4.
