Answer Key

Total Problems: 10

1.57−24

= 3/14

1. Find Least Common Denominator (LCD) of 7 and 4: LCD = 28

2. Convert to Equivalent Fractions: 5/7 = 20/28 and 2/4 = 14/28

3. Subtract Numerators: (20 − 14) / 28 = 6/28

4. Simplify to Lowest Terms: 3/14

2.57−23

= 1/21

1. Find Least Common Denominator (LCD) of 7 and 3: LCD = 21

2. Convert to Equivalent Fractions: 5/7 = 15/21 and 2/3 = 14/21

3. Subtract Numerators: (15 − 14) / 21 = 1/21

3.37−17

= 2/7

1. Like Denominators: Keep denominator 7

2. Subtract Numerators: 3 − 1 = 2 → 2/7

4.67−49

= 26/63

1. Find Least Common Denominator (LCD) of 7 and 9: LCD = 63

2. Convert to Equivalent Fractions: 6/7 = 54/63 and 4/9 = 28/63

3. Subtract Numerators: (54 − 28) / 63 = 26/63

5.58−59

= 5/72

1. Find Least Common Denominator (LCD) of 8 and 9: LCD = 72

2. Convert to Equivalent Fractions: 5/8 = 45/72 and 5/9 = 40/72

3. Subtract Numerators: (45 − 40) / 72 = 5/72

6.710−14

= 9/20

1. Find Least Common Denominator (LCD) of 10 and 4: LCD = 20

2. Convert to Equivalent Fractions: 7/10 = 14/20 and 1/4 = 5/20

3. Subtract Numerators: (14 − 5) / 20 = 9/20

7.35−12

= 1/10

1. Find Least Common Denominator (LCD) of 5 and 2: LCD = 10

2. Convert to Equivalent Fractions: 3/5 = 6/10 and 1/2 = 5/10

3. Subtract Numerators: (6 − 5) / 10 = 1/10

8.23−18

= 13/24

1. Find Least Common Denominator (LCD) of 3 and 8: LCD = 24

2. Convert to Equivalent Fractions: 2/3 = 16/24 and 1/8 = 3/24

3. Subtract Numerators: (16 − 3) / 24 = 13/24

9.38−18

= 1/4

1. Like Denominators: Keep denominator 8

2. Subtract Numerators: 3 − 1 = 2 → 2/8

3. Simplify to Lowest Terms: 1/4

10.23−25

= 4/15

1. Find Least Common Denominator (LCD) of 3 and 5: LCD = 15

2. Convert to Equivalent Fractions: 2/3 = 10/15 and 2/5 = 6/15

3. Subtract Numerators: (10 − 6) / 15 = 4/15
