Question

Noah bought 1/2 pound of candy to share with his friends.They ate 3/8 pound of the candy.How much candy does Noah have left?

Answer 1

you need common denominators so change 1/2 to 4/8
then 4/8-3/8=
1/8 of a pound left

Answer 2

Total pound of candy with Noah =
`(1)/(2)`

Total pound of candy eaten by his friends =
`(3)/(8)` of
`(1)/(2)`

=
`(3)/(8) * (1)/(2)`

=
`(3)/(16)`

Pound of candy left with Noah =
`(1)/(2) - (3)/(16)`

=
`(8-3)/(16)`

=
`(5)/(16)` pound

Therefore,
`(5)/(16)` pound of candy is left with Noah.
