Question

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

Answer 1

We will divide
4/5 ÷ 1/20
4/5 × 20/1
=16
Therefore 16 pieces can e made from that rod

Answer 2

16 pieces.

Explanation:

Length of a metal rod =
`(4)/(5)` meters

This rod is cut in small pieces of length =
`(1)/(20)` meters

To calculate the number of pieces of the rod we will use the formula

Length of the rod = number of pieces × length of one piece

`(4)/(5)` =
`(1)/(20)` × length of one piece

Length of piece =
`((4)/(5))/((1)/(20))`

=
`((4)/(5))* (20)/(1)`

=
`(4* 20)/(5)`

= 16 pieces

Therefore, 16 pieces can be made from the rod.
