A roll of cable measures 18 3/4 feet. After 6 1/2 feet is cut away, how much cable is left on the roll?

Correct answer to question 131 (Arithmetic Reasoning): 12 1/4 feet

Method

Subtract the whole numbers and the fractions separately. 18 minus 6 is 12, and 3/4 minus 1/2 is 1/4, so the cable left on the roll is 12 1/4 feet.
