Question

Solve using equivalent ratios. The first one has been done for you. 5. Jackie has a poster that is 8 inches by 11 inches. She wants to enlarge it so that its length is 33 inches. What should the width be?

Answer 1

To find the width of the enlarged poster, we can set up an equivalent ratio between the length and width. Using the original length and width measurements, we can solve for the width by setting up a proportion and cross multiplying.

Step-by-step explanation:

To solve this problem, we can set up an equivalent ratio between the length and width of the poster. Since the original length is 8 inches and the length after enlarging is 33 inches, we can set up the ratio 8:33. We can then use this ratio to find the width by setting up another ratio. If we have the ratio 8:33 for the length, we need to find the ratio for the width. The original width is 11 inches, so we can set up the ratio 8:11 for the width. Now, we can solve for the width by cross multiplying: 8 * x = 33 * 11. Solving for x, we find that the width should be 27.5 inches.
