Simplifying Fractions

To solve the given expression involving fractions, we need to simplify each fraction and then perform the required operations. Let's simplify the fractions one by one.

1. 11/15 - 6/10 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 15 and 10 is 30. Let's convert both fractions to have a denominator of 30: - 11/15 = 22/30 - 6/10 = 18/30

Now, we can subtract the fractions: - 22/30 - 18/30 = 4/30 = 2/15.

2. 43/66 + 1/42 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 66 and 42 is 1386. Let's convert both fractions to have a denominator of 1386: - 43/66 = 903/1386 - 1/42 = 33/1386

Now, we can add the fractions: - 903/1386 + 33/1386 = 936/1386 = 52/77.

3. 1/3 - 2/7 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 3 and 7 is 21. Let's convert both fractions to have a denominator of 21: - 1/3 = 7/21 - 2/7 = 6/21

Now, we can subtract the fractions: - 7/21 - 6/21 = 1/21.

4. 52/56 + 13/104 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 56 and 104 is 728. Let's convert both fractions to have a denominator of 728: - 52/56 = 364/728 - 13/104 = 91/728

Now, we can add the fractions: - 364/728 + 91/728 = 455/728.

5. 45/52 - 3/28 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 52 and 28 is 364. Let's convert both fractions to have a denominator of 364: - 45/52 = 315/364 - 3/28 = 39/364

Now, we can subtract the fractions: - 315/364 - 39/364 = 276/364.

6. 16/33 + 13/33 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 33 is 33 itself. Both fractions already have the same denominator, so we can directly add them: - 16/33 + 13/33 = 29/33.

7. 15/21 - 21/91 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 21 and 91 is 273. Let's convert both fractions to have a denominator of 273: - 15/21 = 195/273 - 21/91 = 63/273

Now, we can subtract the fractions: - 195/273 - 63/273 = 132/273.

8. 10/21 + 20/77 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 21 and 77 is 231. Let's convert both fractions to have a denominator of 231: - 10/21 = 110/231 - 20/77 = 60/231

Now, we can add the fractions: - 110/231 + 60/231 = 170/231.

9. 15/24 - 2/88 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 24 and 88 is 264. Let's convert both fractions to have a denominator of 264: - 15/24 = 165/264 - 2/88 = 6/264

Now, we can subtract the fractions: - 165/264 - 6/264 = 159/264.

10. 42/4 + 42/10 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 4 and 10 is 20. Let's convert both fractions to have a denominator of 20: - 42/4 = 210/20 - 42/10 = 84/20

Now, we can add the fractions: - 210/20 + 84/20 = 294/20 = 147/10.

11. 11/13 - 1/5 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 13 and 5 is 65. Let's convert both fractions to have a denominator of 65: - 11/13 = 55/65 - 1/5 = 13/65

Now, we can subtract the fractions: - 55/65 - 13/65 = 42/65.

12. 62/99 + 81/99 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 99 is 99 itself. Both fractions already have the same denominator, so we can directly add them: - 62/99 + 81/99 = 143/99.

13. 7/25 - 13/65 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 25 and 65 is 325. Let's convert both fractions to have a denominator of 325: - 7/25 = 91/325 - 13/65 = 13/325

Now, we can subtract the fractions: - 91/325 - 13/325 = 78/325.

14. 2/5 + 1/2 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 5 and 2 is 10. Let's convert both fractions to have a denominator of 10: - 2/5 = 4/10 - 1/2 = 5/10

Now, we can add the fractions: - 4/10 + 5/10 = 9/10.

15. 39/78 - 36/78 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 78 is 78 itself. Both fractions already have the same denominator, so we can directly subtract them: - 39/78 - 36/78 = 3/78.

16. 12/14 + 7/10 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 14 and 10 is 70. Let's convert both fractions to have a denominator of 70: - 12/14 = 30/70 - 7/10 = 49/70

Now, we can add the fractions: - 30/70 + 49/70 = 79/70.

17. 20/21 - 6/21 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 21 is 21 itself. Both fractions already have the same denominator, so we can directly subtract them: - 20/21 - 6/21 = 14/21 = 2/3.

18. 62/104 + 15/16 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 104 and 16 is 208. Let's convert both fractions to have a denominator of 208: - 62/104 = 119/208 - 15/16 = 195/208

Now, we can add the fractions: - 119/208 + 195/208 = 314/208.

19. 17/33 - 1/15 To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 33 and 15 is 165. Let's convert both fractions to have a denominator of 165: - 17/33 = 85/165 - 1/15 = 11/165

Now, we can subtract the fractions: - 85/165 - 11/165 = 74/165.

20. 14/8 + 43/12 To add fractions, we need to have a common denominator. The least common multiple (LCM) of 8 and 12 is 24. Let's convert both fractions to have a denominator of 24: - 14/8 = 42/24 - 43/12 = 86/24
