Question

The table shows the width and length of different pictures that Coby has enlarged for the school yearbook:

Enlarged Pictures
Width (inch) Length (inch)
3 7
6 14
9 21


Based on the table, what is the length of a picture that has a width of 18 inches?

Answer 1

Here, ratio of length to width is:
7/3 = 14/6 = 21/9 = 2.33
So, if width is 18 inches, length would be: 2.33 * 18 = 42

In short, Your Answer would be 42 inches

Hope this helps!
