Question

Mindy is the head cheerleader on her suad. She is making banners to place throughout the school for the first football game of the season. She used ⅔ cup of glitter to make 1 cup of glittery paint. Using this same proportion, how many cups of glitter will Mindy use to make 9 cups of glittery paint?

Answer 1

Answer:

$6\:\text{cups}$

Step-by-step explanation:

Since the proportion is maintained, we can set up the following proportion:

$\frac{2/3}{1}=\frac{x}{9}$, where $x$ is the amount of glitter, in cups, Mindy will use to make 9 cups of glittery paint.

Cross-multiply to get:

$1x=9\cdot \frac{2}{3},\\x=9\cdot \frac{2}{3}=\boxed{6\:\text{cups}}$
