Question

Please help!

Lila wanted to make some baked goods for the bake sale at her school. She used 1/8 lb less flour to make bread than to make cookies. She used 1/4 lb more to make cookies than to make brownies. If she used 1/2 lb of flour to make bread, how much flour did she use to make the brownies? Explain your answer using a diagram and/or an equation or words.

Answer 1

1 and a half pound
because...
1/2+1/8= cookies
cookies-1/4= brownies

Answer 2

Answer: She used 3/8 lb of flour to make the bownies.

Explanation:

Hi, to answer this question we have to write equations with the information given:

• She used 1/2 lb of flour to make bread

Bread = 1/2

• She used 1/8 lb less flour to make bread than to make cookies.

Bread = cookies -1/8

Since bread= 1/2

(1/2) = cookies -1/8

1/2 + 1/8 = cookies

Cookies = 1/2+ 1/8 = 4/8+1/8=5/8

• She used 1/4 lb more to make cookies than to make brownies.

Cookies = brownies + 1/4

Since cookies=5/8

5/8 = brownies + 1/4

5/8 -1/4 = brownies

Brownies = 5/8-1/4 = 5/8 - 2/8 = 3/8

She used 3/8 lb of flour to make the brownies.
