Answer:
[tex](\frac{3}{8})[/tex] lb
Step-by-step explanation:
Lila uses [tex](\frac{1}{2})[/tex] lb of flour to make the bread.
Since she uses [tex](\frac{1}{8})[/tex] lb less to make bread than cookies then flour used to make the cookies = [tex]\frac{1}{2}[/tex] - [tex]\frac{1}{8}[/tex]
= [tex]\frac{4+1}{8}[/tex]
= [tex](\frac{5}{8})[/tex] lb
She used [tex](\frac{1}{4})[/tex]lb more flour to make cookies than brownies then flour used to make brownies = [tex]\frac{5}{8}[/tex] - [tex]\frac{1}{4}[/tex]
= [tex]\frac{5-2}{8}[/tex] = [tex](\frac{3}{8})[/tex] lb
Therefore, flour used to make brownies in [tex](\frac{3}{8})[/tex] lb.
