Answer key · Comparing unlike fractions
1. 2/4
Rename to a common denominator of 4 × 5 = 20.
2/4 = 10/20 and 2/5 = 8/20.
10 > 8, so 2/4 is larger.
2. 3/4
Rename to a common denominator of 4 × 5 = 20.
3/4 = 15/20 and 1/5 = 4/20.
15 > 4, so 3/4 is larger.
3. 2/3
Rename to a common denominator of 3 × 5 = 15.
2/3 = 10/15 and 1/5 = 3/15.
10 > 3, so 2/3 is larger.
4. 1/2
Rename to a common denominator of 2 × 3 = 6.
1/2 = 3/6 and 1/3 = 2/6.
3 > 2, so 1/2 is larger.
5. 2/3
Rename to a common denominator of 3 × 4 = 12.
2/3 = 8/12 and 1/4 = 3/12.
8 > 3, so 2/3 is larger.
