Explanation:

Step1: Calculate total flour needed

Find sum of flour for cake and muffin batter. $\frac{3}{4}+\frac{2}{3}$.
First, find common - denominator. The common denominator of 4 and 3 is 12.
$\frac{3}{4}=\frac{3\times3}{4\times3}=\frac{9}{12}$ and $\frac{2}{3}=\frac{2\times4}{3\times4}=\frac{8}{12}$.
Then $\frac{3}{4}+\frac{2}{3}=\frac{9}{12}+\frac{8}{12}=\frac{9 + 8}{12}=\frac{17}{12}$ cups.

Step2: Calculate additional flour

Subtract the flour on - hand from the total needed.
We have 1 cup on hand, and 1 can be written as $\frac{12}{12}$.
The additional flour needed is $\frac{17}{12}-\frac{12}{12}=\frac{17 - 12}{12}=\frac{5}{12}$ cups.

Answer:

$\frac{5}{12}$
