Question

A barrel of water is full. It decreased by 85%. Now it has 120 liters. How much liters did it have to begin with?

Answer 1

the answer is about 141.18 liters

Explanation:

solve this problem by setting up a proportion. 85/100 = 120/x. then solve for x by cross-multiplying. 85x = 120*100. then simplify. x= 2400/17 or 141.18
