Question

cassie is baking cookies from scratch her recipe calls for 7/8 of a cup of sugar per batch if she is baking just 2/3 oa a batch how much sugar should she use

Answer 1

7/8 =21/24

2/3 x 21 =14

14/24 = 7/12

Cassie should use 7/12 of a cup of sugar

Answer 2

Given:

Amount of sugar required to bake one batch of cookies = $\frac{7}{8}$ of a cup.

Amount of cookies she wants to bake = $\frac{2}{3}$ of a batch.

To Find:

Amount of sugar required to make $\frac{2}{3}$ of a batch of cookies.

Solution:

We shall proceed to solve the given question by using unitary method.

Since,

Amount of sugar required to bake 1 batch of cookies = $\frac{7}{8}$ of a cup.

Then,

Amount of sugar required to bake $\frac{2}{3}$ of a batch of cookies = $\frac{2}{3} \times \frac{7}{8} = \frac{14}{24}$

                                                                                                = $\frac{7}{12}$ of a cup.

Therefore,

Cassie should use $\frac{7}{12}$ of a cup of sugar to bake $\frac{2}{3}$ of a batch of cookies.
