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

Since the picture is enlarged proportionally, the ratio of width to height remains the same. Let the new width be $x$. The proportion is $\frac{6}{4}=\frac{x}{15}$.

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:

$22.5$
