Question

A metal rod will be cut into pieces that are each 1/20 meters long. The rod is 4/5 meters long. How many pieces will be made from the rod?
Write your answer in simplest form.

Answer 1

There will be 16 pieces made from the rod

4/5 ÷ 1/20

Reciprocate 1/20
4/5 ÷ 20/1

Multiply numerators and denominators of both fractions:
4 x 20 = 80
5 x 1 = 5

80/5 sinplified is 16.
