Question

Howie works at a petting zoo. He fed a piglet 1/5 of a bottle of milk then gave 3/4 of what was left to the calf. How much of the bottle of milk did the calf drink

Answer 1

`(3)/(5)`th part of the bottle will be drunk by the calf.

Explanation:

Part of the bottle fed by the piglet =
`(1)/(5)`

Milk left in the bottle = 1 -
`(1)/(5)`

=
`(5-1)/(5)`

=
`(4)/(5)`

Milk drunk by the calf =
`(3)/(4)`th of the left part

=
`(3)/(4)* (4)/(5)`

=
`(3)/(5)`th part of the bottle

Therefore,
`(3)/(5)`th part of the bottle will be drunk by the calf.
