Question

an image of a painting on a website is 5 inches wide and 6 inches tall on the computer screen. the actual height of the painting is 18 inches. what scale is being used for the image on the website? every 1 inch on the computer screen image represents □ inches on the actual painting.

Explanation:

Step1: Set up the proportion

Let $x$ be the number of inches on the actual painting represented by 1 inch on the screen. We know that the height on the screen is 6 inches and the actual height is 18 inches. The proportion is $\frac{1}{x}=\frac{6}{18}$.

Step2: Solve the proportion

Cross - multiply: $6x = 18$. Then divide both sides by 6: $x=\frac{18}{6}=3$.
