Convert to Improper Fractions: Step $1$ : Convert mixed numbers to improper fractions for easier calculation. $\newline$ $13 \frac{7}{12}$ becomes $(12\times13 + 7)/12 = \frac{163}{12}$ . $\newline$ $6 \frac{11}{12}$ becomes $(12\times6 + 11)/12 = \frac{83}{12}$ .
Find Milk Difference: Step $2$ : Subtract the amount of nonfat milk from the amount of whole milk to find the difference. $\frac{163}{12} - \frac{83}{12} = \frac{163 - 83}{12} = \frac{80}{12}.$
Simplify Fraction: Step $3$ : Simplify the fraction $\frac{80}{12}$ to its lowest terms. $\newline$ $\frac{80}{12} = \frac{20}{3}$ , which is $6 \frac{2}{3}$ when converted to a mixed number.
