Chapter 6, Problem 11STP

To determine

To calculate:Tofind how much flour does Miley need in all

Answer to Problem 11STP

  $1\frac{5}{6}$ cups of flour is needed in all

Explanation of Solution

Given information:Miley needs to use $\frac{1}{4}$ cup of flour in one recipe and $\frac{2}{3}$ cup in second recipe.

Calculation:

Given that Miley needs to use $\frac{1}{4}$ cup of flour in one recipe and $\frac{2}{3}$ cup in second recipe.

Also, given that Miley doubles both recipes.

Thus,

Amount of flour needed for first recipe $=2\times \frac{1}{4}=\frac{1}{2}cups$

Amount of flour needed for second recipe $=2\times \frac{2}{3}=\frac{4}{3}cups$

Now, total flour needed is calculated as

$\begin{array}{l}Total=\frac{1}{2}+\frac{4}{3}\\ Total=\frac{1\times 3}{2\times 3}+\frac{4\times 2}{3\times 2}\\ Total=\frac{3}{6}+\frac{8}{6}\\ Total=\frac{11}{6}\\ Total=1\frac{5}{6}\end{array}$

Hence, $1\frac{5}{6}$ cups of flour is needed in all
