Answer 1

1/4 + 3/5 = 5/20 + 12/20 = 17/20
9/11 - 2/5 = 45/55 - 22/55 = 23/55
13/26 - 9/32 = 416/832 - 234/832 = 182/832 = 91/416 
3/28 + 5/14 = 3/28 + 10/28 = 13/28
14/15- 7/10 = 28/30 - 21/30 = 7/30
3/8 + 1/6 = 9/24 + 4/24 = 13/24
9/25 - 7/20 = 72/200 - 70/200 = 2/200 = 1/100
37/42 - 17/24 = 296/336 - 238/336 = 58/336 = 29/168
11/24 - 3/6 = 11/24 - 12/24 = - 1/24
9/16 + 7/24 - 3/8 = 27/48 + 14/48 - 18/48 = 23/48

1/3-1/6+1/4 = 4/12 - 2/12 + 3/12 = 5/12
2/5+4/15-5/29 = 3/15 + 4/15 - 5/29 = 7/15 - 5/29 = 203/435 - 75/435 = 128/435

Answer 2

To solve the given arithmetic expressions, let's go through each one step by step:

1. 1/4 + 3/5: To add fractions, we need to find a common denominator. In this case, the common denominator is 20. So, we have: 1/4 = 5/20 3/5 = 12/20

Adding them together, we get: 5/20 + 12/20 = 17/20

Therefore, 1/4 + 3/5 = 17/20.

2. 9/11 - 2/5: To subtract fractions, we also need a common denominator. The common denominator here is 55. So, we have: 9/11 = 45/55 2/5 = 22/55

Subtracting them, we get: 45/55 - 22/55 = 23/55

Therefore, 9/11 - 2/5 = 23/55.

3. 13/16 - 9/32: Again, we need a common denominator to subtract fractions. The common denominator here is 32. So, we have: 13/16 = 26/32 9/32 = 9/32

Subtracting them, we get: 26/32 - 9/32 = 17/32

Therefore, 13/16 - 9/32 = 17/32.

4. 3/28 + 5/14: To add fractions, we need a common denominator. The common denominator here is 28. So, we have: 3/28 = 3/28 5/14 = 10/28

Adding them, we get: 3/28 + 10/28 = 13/28

Therefore, 3/28 + 5/14 = 13/28.

5. 14/15 - 7/10: To subtract fractions, we need a common denominator. The common denominator here is 30. So, we have: 14/15 = 28/30 7/10 = 21/30

Subtracting them, we get: 28/30 - 21/30 = 7/30

Therefore, 14/15 - 7/10 = 7/30.

6. 3/8 + 1/6: To add fractions, we need a common denominator. The common denominator here is 24. So, we have: 3/8 = 9/24 1/6 = 4/24

Adding them, we get: 9/24 + 4/24 = 13/24

Therefore, 3/8 + 1/6 = 13/24.

7. 9/25 - 7/20: To subtract fractions, we need a common denominator. The common denominator here is 100. So, we have: 9/25 = 36/100 7/20 = 35/100

Subtracting them, we get: 36/100 - 35/100 = 1/100

Therefore, 9/25 - 7/20 = 1/100.

8. 37/42 - 17/24: To subtract fractions, we need a common denominator. The common denominator here is 168. So, we have: 37/42 = 70/168 17/24 = 119/168

Subtracting them, we get: 70/168 - 119/168 = -49/168

Therefore, 37/42 - 17/24 = -49/168.

9. 11/24 - 3/6: To subtract fractions, we need a common denominator. The common denominator here is 24. So, we have: 11/24 = 11/24 3/6 = 12/24

Subtracting them, we get: 11/24 - 12/24 = -1/24

Therefore, 11/24 - 3/6 = -1/24.

10. 9/16 + 7/24 - 3/8: To add or subtract fractions, we need a common denominator. The common denominator here is 48. So, we have: 9/16 = 27/48 7/24 = 14/48 3/8 = 18/48

Adding them together, we get: 27/48 + 14/48 - 18/48 = 23/48

Therefore, 9/16 + 7/24 - 3/8 = 23/48.

11. 1/3 - 1/6 + 1/4: To add or subtract fractions, we need a common denominator. The common denominator here is 12. So, we have: 1/3 = 4/12 1/6 = 2/12 1/4 = 3/12

Adding them together, we get: 4/12 - 2/12 + 3/12 = 5/12

Therefore, 1/3 - 1/6 + 1/4 = 5/12.

12. 2/5 + 4/15 - 5/29: To add or subtract fractions, we need a common denominator. The common denominator here is 435. So, we have: 2/5 = 174/435 4/15 = 116/435 5/29 = 15/87

Adding them together, we get: 174/435 + 116/435 - 15/87 = 275/435

Therefore, 2/5 + 4/15 - 5/29 = 275/435.

I hope this helps! Let me know if you have any further questions.
