Subtraction of Fractions

To perform the subtraction of fractions, we need to find a common denominator for each pair of fractions and then subtract the numerators. Let's solve each subtraction problem step by step:

1. 5/9 - 13/27: - The common denominator for 9 and 27 is 27. - Converting both fractions to have a denominator of 27, we get: - 5/9 = 15/27 - 13/27 remains the same. - Subtracting the numerators, we have: - 15/27 - 13/27 = 2/27

2. 3/8 - 5/24: - The common denominator for 8 and 24 is 24. - Converting both fractions to have a denominator of 24, we get: - 3/8 = 9/24 - 5/24 remains the same. - Subtracting the numerators, we have: - 9/24 - 5/24 = 4/24 = 1/6

3. 2/5 - 3/8: - The common denominator for 5 and 8 is 40. - Converting both fractions to have a denominator of 40, we get: - 2/5 = 16/40 - 3/8 = 15/40 - Subtracting the numerators, we have: - 16/40 - 15/40 = 1/40

4. 5/12 - 13/72: - The common denominator for 12 and 72 is 72. - Converting both fractions to have a denominator of 72, we get: - 5/12 = 30/72 - 13/72 remains the same. - Subtracting the numerators, we have: - 30/72 - 13/72 = 17/72

5. 3/5 - 17: - We can rewrite 17 as a fraction with a denominator of 1: 17/1. - The common denominator for 5 and 1 is 5. - Converting both fractions to have a denominator of 5, we get: - 3/5 remains the same. - 17/1 = 85/5 - Subtracting the numerators, we have: - 3/5 - 85/5 = -82/5

6. 7/15 - 2/9: - The common denominator for 15 and 9 is 45. - Converting both fractions to have a denominator of 45, we get: - 7/15 = 21/45 - 2/9 = 10/45 - Subtracting the numerators, we have: - 21/45 - 10/45 = 11/45

7. 11/12 - 19/60: - The common denominator for 12 and 60 is 60. - Converting both fractions to have a denominator of 60, we get: - 11/12 = 55/60 - 19/60 remains the same. - Subtracting the numerators, we have: - 55/60 - 19/60 = 36/60 = 3/5

8. 9/17 - 27/68: - The common denominator for 17 and 68 is 68. - Converting both fractions to have a denominator of 68, we get: - 9/17 = 36/68 - 27/68 remains the same. - Subtracting the numerators, we have: - 36/68 - 27/68 = 9/68

9. 2/3 - 5/16: - The common denominator for 3 and 16 is 48. - Converting both fractions to have a denominator of 48, we get: - 2/3 = 32/48 - 5/16 = 15/48 - Subtracting the numerators, we have: - 32/48 - 15/48 = 17/48

10. 9/10 - 4/15: - The common denominator for 10 and 15 is 30. - Converting both fractions to have a denominator of 30, we get: - 9/10 = 27/30 - 4/15 = 8/30 - Subtracting the numerators, we have: - 27/30 - 8/30 = 19/30

11. 4/15 - 11/60: - The common denominator for 15 and 60 is 60. - Converting both fractions to have a denominator of 60, we get: - 4/15 = 16/60 - 11/60 remains the same. - Subtracting the numerators, we have: - 16/60 - 11/60 = 5/60 = 1/12

12. 5/8 - 1/3: - The common denominator for 8 and 3 is 24. - Converting both fractions to have a denominator of 24, we get: - 5/8 = 15/24 - 1/3 = 8/24 - Subtracting the numerators, we have: - 15/24 - 8/24 = 7/24

Now let's summarize the results:

- 5/9 - 13/27 = 2/27 - 3/8 - 5/24 = 1/6 - 2/5 - 3/8 = 1/40 - 5/12 - 13/72 = 17/72 - 3/5 - 17 = -82/5 - 7/15 - 2/9 = 11/45 - 11/12 - 19/60 = 3/5 - 9/17 - 27/68 = 9/68 - 2/3 - 5/16 = 17/48 - 9/10 - 4/15 = 19/30 - 4/15 - 11/60 = 1/12 - 5/8 - 1/3 = 7/24
