At a deli counter,

• Someone bought \(1 \frac34\) pounds of ham for \$14.50.
• Someone bought \(2 \frac12\) pounds of turkey for \$26.25.
• Someone bought \(\frac38\) pound of roast beef for \$5.50.

Which meat is the least expensive per pound? Which meat is the most expensive per pound? Explain how you know.

A phone’s battery is out of power. After charging for \(\frac{1}{3}\) of an hour, the battery is at \(\frac{2}{5}\) of its full power. How long (in total) will it take the battery to charge completely?

Decide whether each equation can represent the situation.

1. \(\frac13\boldcdot {?}=\frac25\)

2. \(\frac13\div \frac25={?}\)

3. \(\frac25 \div \frac13 ={?}\)

4. \(\frac25 \boldcdot {?}=\frac13\)

Find each quotient.

1. \(5 \div \frac{1}{10}\)

2. \(5 \div \frac{3}{10}\)

3. \(5\div \frac{9}{10}\)

Consider the problem: It takes one week for a crew of workers to pave \(\frac35\) kilometer of a road. At that rate, how long will it take to pave 1 kilometer?

Write a multiplication equation and a division equation to represent the question. Then find the answer and show your reasoning.
