Lesson 9: Practice Problems

Problem 1

A group of friends is sharing $2 \frac{1}{2}$ pounds of berries.

If each friend received $\frac{5}{4}$ of a pound of berries, how many friends are sharing the berries?
If 5 friends are sharing the berries, how many pounds of berries does each friend receive?

Problem 2

$\frac{2}{5}$ kilogram of soil fills $\frac{1}{3}$ of a container. Can 1 kilogram of soil fit in the container? Explain or show your reasoning.

Problem 3

After raining for $\frac{3}{4}$ of an hour, a rain gauge is $\frac{2}{5}$ filled. If it continues to rain at that rate for 15 more minutes, what fraction of the rain gauge will be filled?

To help answer this question, Diego wrote the division equation $\frac{3}{4} \div \frac{2}{5} = ?$ . Explain why this equation does not represent the situation.
Write a multiplication equation and a division equation that does represent the situation.
