to show how much mina buys

Answer 1

The bananas weigh 1
`(7)/(8)` pounds

Explanation:

How many pounds of apples?

5
`(3)/(4)` - (2
`(1)/(2)` + 1
`(3)/(8)`)

5
`(3)/(4)` -( 2
`(4)/(8)` + 1
`(3)/(8)`) I multiplied
`(1)/(2)` x
`(4)/(4)` to get
`(4)/(8)`

5
`(3)/(4)` - 3
`(7)/(8)`

5
`(6)/(8)` - 3
`(7)/(8)` I multiplied
`(3)/(4)` x
`(2)/(2)` to get
`(6)/(8)`

(4
`(8)/(8)` +
`(6)/(8)`) - 3
`(7)/(8)` I rewrote 5
`(6)/(8)` so I could regroup ( 1 means the same as
`(8)/(8)`

4
`(14)/(8)` - 3
`(7)/(8)`

1
`(7)/(8)`
