Question

One serving of chad's cereal is 1 1/4 ounces. How many servins are in 15 1/3 ounces box?

Answer 1

12

change the mixed numbers to improper fractions before dividing

1 $\frac{1}{4}$ = $\frac{5}{4}$ and 15 $\frac{1}{3}$ = $\frac{46}{3}$

divide contents of box by a serving

$\frac{46}{3}$ ÷ $\frac{5}{4}$

change ÷ to × and turn the second fraction upside down

= $\frac{46}{3}$ × $\frac{4}{5}$

= $\frac{184}{15}$ = 12.26666 = 12 complete servings
