Answer 2

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.
