A person on a diet goes from 160lb to a weight of 136lb. What is the percent decrease?

Question

What steps are needed to be done to solve this problem? 

Answer 1

Difference/original = (160 - 136)/160 = 24/160 = 0.15 = 15% decrease.

 

Let's say it was the other way and he gained weight from 136 to 160. Then it would be 24/136 = 0.176 = 18% increase.

 

Hope this helps!
