Question

You are wrapping boxes for a fund-raiser. You have 80 large boxes. You need 2 and three-fourths feet of ribbon for each large box. Each roll of ribbon has 50 feet of ribbon.

Answer 1

5 rolls of ribbon are needed

Explanation:

To find how much ribbon you'll use, multiply 80 by 2 3/4. To multiply them, convert 2 3/4 into an improper fraction 11/4.

Multiply: 80 * 11/4 = 880/4 = 220

This means you need 220 total feet of ribbon. Since each roll has 50 feet, you'll need 5 rolls or 250 feet to wrap every box.
