Sarah has a picture that fits a 3 inch wide by 5 inch long picture frame. She wants to make the picture proportionately bigger so the picture fits a frame with a length of 15 inches. What would the width of the frame need to be?

9 inches

Step-by-step explanation:

So the proportions are 3 by 5, and she wants to make the length 15

To make the length 15, you need to multiply the length by 3 (5*3)

Because it is proportional, you also multiply the width by 3

3*3 = 9

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
