Bongie decides to make the cupcake batter. She uses 3/4 cup of sugar, 1/2 cup of flour, and 1/3 cup of butter. How much flour did Bongie use compared to the total amount of sugar and butter combined?

Bongie used $\frac{1}{2}$ cup of flour.

Amount of sugar = $\frac{3}{4}$ cup
Amount of butter = $\frac{1}{3}$ cup
Total amount of sugar and butter = $\frac{3}{4} + \frac{1}{3}$

To add these fractions, find a common denominator, which is 12.

Now, add the fractions:

This comparison is expressed as a ratio: $\frac{\text{Amount of flour}}{\text{Total amount of sugar and butter}}$.

To simplify this complex fraction, multiply the numerator by the reciprocal of the denominator:

Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2:

Bongie used $\frac{6}{13}$ as much flour compared to the total amount of sugar and butter combined.
