A cylindrical rod is 1.6 meters long. It is cut into pieces 3/5 meters in length. How many whole pieces can be made, and what length remains?
Show answer & explanation
Correct answer: A
Explanation
Total length = 1.6 meters
Length of each piece = 3/5 meters
Number of pieces = Total length ÷ Length per piece
(8/5) ÷ (3/5) = 8/5 × 5/3 = 8/3
Number of whole pieces = 2
Length used = 2 × 3/5 = 6/5
Remaining length = 8/5 − 6/5 = 2/5
2 pieces; 2/5 meters remain.
