A water tank holds 240 gallons when full. If the tank is currently 3/8 full, how many gallons does it contain?

Correct answer to question 4 (Arithmetic Reasoning): 90 gallons

Method

Finding a fraction of an amount means multiplying. One eighth of 240 gallons is 30 gallons, so three eighths is 3 x 30 = 90 gallons.
