Converting Measurements — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
There are 10 inches in 1 foot.
Corrected: There are 12 inches in 1 foot.
The corrected sentence is: "There are 12 inches in 1 foot.". The original sentence "There are 10 inches in 1 foot." contained an error that needed to be fixed.
2. Fix the sentence:
5 pounds = 50 ounces
Corrected: 5 pounds = 80 ounces because there are 16 ounces in 1 pound and 5 × 16 = 80.
The corrected sentence is: "5 pounds = 80 ounces because there are 16 ounces in 1 pound and 5 × 16 = 80.". The original sentence "5 pounds = 50 ounces" contained an error that needed to be fixed.
3. Fix the sentence:
2 yards = 8 feet
Corrected: 2 yards = 6 feet because there are 3 feet in 1 yard and 2 × 3 = 6.
The corrected sentence is: "2 yards = 6 feet because there are 3 feet in 1 yard and 2 × 3 = 6.". The original sentence "2 yards = 8 feet" contained an error that needed to be fixed.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 3 feet = 36 inches
There are 12 inches in 1 foot. 3 × 12 = 36 inches.
2. 48 ounces = 3 pounds
There are 16 ounces in 1 pound. 48 ÷ 16 = 3 pounds.
3. 4 yards = 12 feet
There are 3 feet in 1 yard. 4 × 3 = 12 feet.
4. 6,000 pounds = 3 tons
There are 2,000 pounds in 1 ton. 6,000 ÷ 2,000 = 3 tons.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A bookshelf is 5 feet tall. How many inches tall is it? Show your work.
Sample answer: 5 × 12 = 60 inches. The bookshelf is 60 inches tall.
To convert feet to inches, multiply by 12 (the number of inches per foot). 5 × 12 = 60 inches.
2. A bag of apples weighs 2 pounds. How many ounces does the bag weigh? Explain your reasoning.
Sample answer: There are 16 ounces in 1 pound, so 2 × 16 = 32 ounces. The bag weighs 32 ounces.
To convert pounds to ounces, multiply by 16 (ounces per pound). 2 × 16 = 32 ounces.
