The table shows the number of each type of seed packet a garden center had remaining at the end of summer. Bags were created with 20 random seed packets in each bag. How many complete bags of seeds can be created?
Explanation
Total packets = 40 + 95 + 160 + 125 + 70 = 490. Number of bags = $490 \div 20 = 24.5$. The number of complete bags is 24.

The table shows the amount of each ingredient Jacob is using to make one pizza. If he has 11 cups of mozzarella cheese and makes the greatest number of whole pizzas possible, how much mozzarella cheese remains?
Explanation
$11 \div \frac{3}{4} = 11 \times \frac{4}{3} = 14 \frac{2}{3}$. He can make 14 whole pizzas. Used cheese = $14 \times \frac{3}{4} = \frac{42}{4} = 10 \frac{1}{2}$ cups. Remainder = $11 - 10 \frac{1}{2} = \frac{1}{2}$ cup.

Romeo had $\frac{3}{4}$ pound of fudge \left. He divided the remaining fudge into $\frac{5}{16}$ pound bags. Write and solve an equation that models the situation. Then interpret the quotient.
Explanation
$\frac{3}{4} \div \frac{5}{16} = \frac{3}{4} \times \frac{16}{5} = \frac{12}{5} = 2 \frac{2}{5}$. This means he can fill 2 whole bags.
