show the math

Answer 1

`7(1)/(2)` cups of flour

Explanation:

Jed is baking shortbread for a bake sale.

The recipe calls for flour =
`1(1)/(4)` cups

and butter =
`(1)/(2)` stick

Jed uses 1 sticks of butter in =
`1(1)/(4)` ÷
`(1)/(2)`

=
`(5)/(4)` ×
`(2)/(1)`

=
`(10)/(4)`

Therefore, Jed will use 3 stick of butter in =
`(10)/(4)` × 3

=
`(30)/(4)`

=
`(15)/(2)`

=
`7(1)/(2)` cups of flour

Jed needs
`7(1)/(2)` cups of flour if he uses 3 sticks of butter.
