Question
A photo shop makes prints of photographs in a variety of sizes. Every print has a length-to-width ratio of 5: 3.5 regardless of its size. A customer Twants a print that is 20 in. long. What is the width of this print?
Step 1
The ratio is 5:3.5, which can be written as $\frac{5}{3.5}$. The length the customer wants is 20 inches, and we want to find the corresponding width, which we'll call $w$. So we can write the proportion as $\frac{5}{3.5} = \frac{20}{w}$. Show more…
