A technician needs washers that are 5/8 inch thick. If washers are stacked to fill a gap of 3 3/4 inches, how many washers are needed?
Pick an answer
Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 140 (Arithmetic Reasoning): 6 washers
Method
Dividing the gap by the washer thickness gives the count. 3 3/4 is 15/4, and dividing 15/4 by 5/8 means multiplying by the reciprocal: 15/4 x 8/5 = 6 washers exactly.
