Question

Matthew used 1/5 of a box of flour for cooking and 3/4 of the remainder to make bread. The rest of the flower was packed equally into 5 containers. What fraction of the total amount of flour was in each container?

Answer 1

So, if the total amount of the flower was x

then he used
`(1)/(5)x` for cooking and
`(4)/(5)x` was left

then he used
`(4*3)/(5*4)x`=
`(3)/(5)x` to make bread and
`(4)/(5)x-(3)/(5)x`=
`(1)/(5)x` was left.


so the
`(1)/(5)x` was packed into 5 containers, each container had


`(1)/(5*5)x`, which is
`(1)/(25)x` of the total amount
