Question

A puddle originally contained 2.5 gallons of water. After a hot day, only 1 gallon of water remains.

What is the percent decrease?

Enter your answer in the box.

%

Answer 1

60%

Explanation:

There is a 60% decrease because 60% of 2.5 = 1.5

So, 2.5 - 1.5 = 1.

Or

1.5/2.5 = 0.60 (which is 60% as a percentage)
