Question 6 • FL-1205040-M/J Grade 7 Mathematics A -GF

One of the dog treats in Shelley’s shop is 8 inches long and 3.2 inches wide. She wants to make a miniature version that has proportional dimensions. If the miniature treat will be 3 inches long, how wide should it be?

Answer
A
1.2 inches
B
1.8 inches
C
2.3 inches
D
3.2 inches

Explanation

The miniature’s dimensions must use the same scale factor in both directions. Its length is scaled by 3 ÷ 8, so its width should be 3.2 × (3 ÷ 8) = 1.2 inches. The miniature treat should be 1.2 inches wide.
