Question

A picture measuring 4" high by 6" wide is to be enlarged so that the width is now 9”. How tall will the picture be?

Answer 1

The original width was 6 inches, the new width is 9 inches.

Divide the new width by the original width to find the scale factor:

9/6 = 1.5

Now multiply the original height by the scale factor to find the new height:

4 x 1.5 = 6 inches.
