Answer:
\(7\frac{1}{2}\) cups of flour
Step-by-step explanation:
Jed is baking shortbread for a bake sale.
The recipe calls for flour = \(1\frac{1}{4}\) cups
and butter = \(\frac{1}{2}\) stick
Jed uses 1 sticks of butter in = \(1\frac{1}{4}\) ÷ \(\frac{1}{2}\)
= \(\frac{5}{4}\) × \(\frac{2}{1}\)
= \(\frac{10}{4}\)
Therefore, Jed will use 3 stick of butter in = \(\frac{10}{4}\) × 3
= \(\frac{30}{4}\)
= \(\frac{15}{2}\)
= \(7\frac{1}{2}\) cups of flour
Jed needs \(7\frac{1}{2}\) cups of flour if he uses 3 sticks of butter.
