Question

Wayne has a recipe on a 3-inch-by-5-inch index card that he wants to enlarge to 15 inches long. How wide will the enlargement be?

Answer 1

Explanation:

If you r trying to find out just multiply by a number that'll give 15 like 5 3times 5 is 15 then multiply both denominator and numerator

Answer 2

I'm not completely sure which way they would like for you to do it but anyways
3 to 15 is a times 5 so 5 times 5 is 25 so a possible width can be 25 as in 15 by 25
or
5 to 15 is times 3so 3 times 3 is 9so a possible width can be 9as in 15 by 9
I personally think 25 inches wide would be the better answer


Hope I Helped :D
