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