Hello there!

72; 3:5
The corresponding number in our ratio for 72 is 3 as 5 cannot be divided evenly into 72.

72 / 3 = 24

This means our scale factor for our ratio is 24, so we must multiply 5 by 24 to find the other portion of the ratio.
24 x 5 = 120

Our new ratio is:
72:120

I hope this helps!
