Answer Key: Fraction to Whole Match-Up!
Problem 1
What fraction equals 1 whole if the number line is divided into halves?
<---|---|---|---|---|
0 1/2 (2/2) 3/2 2
Fraction for 1 whole: 2/2
Thought Process: The number line is divided into halves. 1 whole means we have both halves, so 2/2 is equal to 1. On the number line, 2/2 is located exactly where 1 is.
Problem 2
What fraction equals 2 wholes if the number line is divided into thirds?
<---|---|---|---|---|---|---|---|---|
0 1/3 2/3 (3/3) 4/3 5/3 (6/3) 3
Fraction for 2 wholes: 6/3
Thought Process: The number line is divided into thirds. To get to 2 wholes, we need 3/3 for the first whole and another 3/3 for the second whole. 3 + 3 = 6, so 6/3 equals 2. On the number line, 6/3 is located exactly where 2 is.
Problem 3
Draw a number line from 0 to 2. Divide each whole into fourths. Then, circle the fraction that represents 1 whole and box the fraction that represents 2 wholes.
<---|---|---|---|---|---|---|---|---|
0 1/4 2/4 3/4 (4/4) 5/4 6/4 7/4 [8/4]
Thought Process: To divide into fourths, each whole (from 0 to 1, and 1 to 2) should have 4 equal parts. One whole is 4/4. Two wholes would be 4/4 + 4/4 = 8/4.
Problem 4
Which of these fractions is equal to a whole number? Circle all that apply.
4/4 3/5 6/2 1/3 7/7
Thought Process: A fraction is equal to a whole number if the numerator is a multiple of the denominator (or the numerator and denominator are the same).
- 4/4 = 1 (whole number)
- 3/5 is not a whole number
- 6/2 = 3 (whole number)
- 1/3 is not a whole number
- 7/7 = 1 (whole number)
Problem 5
Explain in your own words how you know when a fraction represents a whole number.
Sample Answer: I know a fraction represents a whole number when the top number (numerator) is the same as the bottom number (denominator), or when the top number can be divided evenly by the bottom number. This means you have enough parts to make one or more full wholes.
