Question

picture jasmine enlarged the size of a picture to a height of 15 inches. what is the new width of the picture if it was originally 6 inches wide by 4 inches tall?

Explanation:

Step1: Set up proportion

Let \( x \) be the new width. The ratio of width to height should be constant. So, \(\frac{6}{4}=\frac{x}{15}\)

Step2: Cross - multiply

Cross - multiplying gives \( 4x = 6\times15 \)

Step3: Solve for \( x \)

First, calculate \( 6\times15=90 \). Then, \( x=\frac{90}{4} = 22.5 \)

Answer:

22.5
