Question

Roberta wants to reduce a drawing that is 12 inches long by 8 inches wide. If her new drawing is 6 inches long, how wide will it be?

Answer 1

It will be 4 inches wide
12/2=6
8/2=4

Answer 2

What does it mean to be proportional?

For two numbers to be proportional, they need to be directly increasing or decreasing in a constant ratio.

If this drawing is proportional, we can see that 12 was divided by 2 to get 6. We can do the same to 8.

8 ÷ 2 = 4

The width of the new drawing is 4.
