Question

lila decided to make more baked goods for bake sale.She uses 1/8 lb less to make bread than to make cookies. She used 1/4 lb more flour to make cookies than to make brownies. If she used 1/2lb of flour to make the bread , how much flour did she use to make the brownies ?

Answer 1

`((3)/(8))` lb

Explanation:

Lila uses
`((1)/(2))` lb of flour to make the bread.

Since she uses
`((1)/(8))` lb less to make bread than cookies then flour used to make the cookies =
`(1)/(2)` -
`(1)/(8)`

=
`(4+1)/(8)`

=
`((5)/(8))` lb

She used
`((1)/(4))`lb more flour to make cookies than brownies then flour used to make brownies =
`(5)/(8)` -
`(1)/(4)`

=
`(5-2)/(8)` =
`((3)/(8))` lb

Therefore, flour used to make brownies in
`((3)/(8))` lb.

Answer 2

Ok so we are trying to find out how much flour she used to make brownies so we already know that she used 1/2 flour to make bread and She uses 1/8 flour less flour to make bread than to make cookies so if we add 1/2 and 1/8 we will get the amount of flour she used to make the cookies so 1/2 + 1/8 = 5/8 so now that we have the amount of flour she used to make the cookies we know that that is 1/4 more flour than brownies so if we subtract 5/8 by 1/4 we will get are answer to how much flour she uses to make brownies so 5/8 - 1/4 = 3/8 and that's your answer do you understand?
