28. How much plain yogurt will you need to make 2 1/2 dozen cookies? Show your work.

xxMikexx [17]

Answer:

$\frac{5}{6}$ cups

Step-by-step explanation:

Normally, when working with mixed numbers, I would prefer to turn them into improper fractions first before evaluating.

1 $\frac{1}{2}$ cookies --- $\frac{1}{2}$ cup plain yogurt

$\frac{3}{2}$ cookies --- $\frac{1}{2}$ cup plain yogurt

2 $\frac{1}{2}$ cookies --- ? cup plain yogurt

$\frac{5}{2}$ cookies --- $\frac{5}{3}$ × $\frac{1}{2}$ cup plain yogurt = $\frac{5}{6}$ cups plain yogurt
