Question

a travel guide has dimensions 8 in. by 10 in. what scale factor should be used to make an enlarged version that has dimensions 12 in. by 15 in.?
0.67
3
1.5
4

Explanation:

Step1: Find scale factor for width

Scale factor = New width / Original width = \( \frac{12}{8} \)
\( \frac{12}{8} = 1.5 \)

Step2: Verify with height

Scale factor = New height / Original height = \( \frac{15}{10} \)
\( \frac{15}{10} = 1.5 \)

Answer:

1.5
