Converting Measurements — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A school hallway is 90 feet long. A classroom is 10 yards wide. Which is longer, and by how many feet?
A) The hallway, by 60 feet
B) The hallway, by 50 feet
C) The classroom, by 30 feet
D) They are the same length
Convert 10 yards to feet: 10 × 3 = 30 feet. The hallway is 90 feet, so the difference is 90 - 30 = 60 feet longer.
2. Jake has 5 quarts of lemonade. Sara has 18 cups of lemonade. Who has more, and by how many cups?
A) Jake, by 4 cups
B) Sara, by 2 cups
C) Jake, by 2 cups
D) Sara, by 4 cups
Convert Jake's 5 quarts to cups: 5 × 4 = 20 cups. Sara has 18 cups, so Jake has 20 - 18 = 2 more cups.
3. A truck can carry 4 tons. It already holds 6,500 pounds of cargo. How many more pounds can it carry?
A) 1,500 pounds
B) 2,500 pounds
C) 3,500 pounds
D) 500 pounds
Convert 4 tons to pounds: 4 × 2,000 = 8,000 pounds. Subtract the cargo already loaded: 8,000 - 6,500 = 1,500 pounds of space remaining.
4. A park path is 3 kilometers long. A jogger runs 2,200 meters. How many more meters must she run to finish?
A) 700 meters
B) 900 meters
C) 800 meters
D) 1,000 meters
Convert 3 kilometers to 3,000 meters, then subtract what she already ran: 3,000 - 2,200 = 800 meters left.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A rope is 7 feet long. A chain is 90 inches long. The chain is 6 inches longer.
Convert 7 feet to inches: 7 × 12 = 84 inches. The chain is 90 inches, so it is 90 - 84 = 6 inches longer.
2. A jug holds 3 gallons. A bottle holds 10 pints. The jug holds 14 more pints.
Convert 3 gallons to pints: 3 × 8 = 24 pints. The bottle holds 10 pints, so the jug holds 24 - 10 = 14 more pints.
3. A watermelon weighs 9,500 grams. A cantaloupe weighs 2.5 kilograms. Together they weigh 12 kilograms.
Convert 9,500 grams to 9.5 kilograms, then add 9.5 + 2.5 = 12 kilograms total.
4. A race is 1 mile long. A runner has completed 4,000 feet. He has 1,280 feet left.
One mile equals 5,280 feet. Subtract the distance already run: 5,280 - 4,000 = 1,280 feet remaining.
5. A tank holds 6 liters. After pouring out 2,750 milliliters, 3,250 milliliters remain.
Convert 6 liters to 6,000 milliliters, then subtract what was poured out: 6,000 - 2,750 = 3,250 milliliters left.
