Question

Colby adds 1 2/3 cups of flour to his mixing bowl and then realizes he put too much.He takes 1/4 cup of flour back out of the bowl.How much flour did colby's recipe call for?

Answer 1

Answer:

The quantity of flour need by Colby's recipe is  $1\frac{5}{12}$ cups.

Step-by-step explanation:

Given: Colby adds $1\frac{2}{3}$ cups of flour to his mixing bowl and then realizes he put too much.He takes$\frac{1}{4}$ cup of flour back out of the bowl.

We have to find the quantity of flour need by Colby's recipe.

The quantity of flour need by Colby's recipe = Number of flour cups Colby added - number of flour cups Colby taken out.

that is,

Number of flour cups Colby added = $1\frac{2}{3}=\frac{5}{3}$

Number of flour cups Colby taken out = $\frac{1}{4}$

The quantity of flour need by Colby's recipe = $\frac{5}{3}-\frac{1}{4}$

taking LCM, we get, LCM(3,4) =12

The quantity of flour need by Colby's recipe = $\frac{20-3}{12}$

The quantity of flour need by Colby's recipe = $\frac{17}{12}=1\frac{5}{12}$

Thus, The quantity of flour need by Colby's recipe is  $1\frac{5}{12}$ cups.
