Answer 2

Let's solve each of the given equations step by step:

1. 5/8 + 5/6: To add these fractions, we need a common denominator. The least common multiple of 8 and 6 is 24. Therefore, we can rewrite the fractions as (15/24) + (20/24) and add them to get: (15/24) + (20/24) = 35/24

2. 3/20 - 1/50: The common denominator for these fractions is 100. Rewriting them with the common denominator gives us (15/100) - (2/100) and subtracting them results in: (15/100) - (2/100) = 13/100

3. 8/51 + 3/17: Here, the common denominator is 51. Rewriting the fractions with the common denominator gives us (8/51) + (9/51) and adding them yields: (8/51) + (9/51) = 17/51

4. 1/3 - 1/6: The common denominator for 3 and 6 is 6. Rewriting the fractions with the common denominator gives us (2/6) - (1/6) and subtracting them gives: (2/6) - (1/6) = 1/6

5. 0.35 - 1/20: To subtract a decimal from a fraction, we convert the decimal to a fraction with the same denominator. Converting 0.35 to a fraction gives us 7/20. Now we can subtract the fractions: 7/20 - 1/20 = 6/20 = 3/10

6. 1/15 - 1/30: The common denominator for 15 and 30 is 30. Rewriting the fractions with the common denominator gives us (2/30) - (1/30) and subtracting them results in: (2/30) - (1/30) = 1/30

7. 3/10 - 2/15: The common denominator for 10 and 15 is 30. Rewriting the fractions with the common denominator gives us (9/30) - (4/30) and subtracting them yields: (9/30) - (4/30) = 5/30 = 1/6

8. 1/6 + 8/9: The common denominator for 6 and 9 is 18. Rewriting the fractions with the common denominator gives us (3/18) + (16/18) and adding them results in: (3/18) + (16/18) = 19/18

9. 3/5 + 0.4: Converting 0.4 to a fraction gives us 2/5. Now we can add the fractions: 3/5 + 2/5 = 5/5 = 1

10. 23/45 + 13/30: The common denominator for 45 and 30 is 90. Rewriting the fractions with the common denominator gives us (46/90) + (39/90) and adding them yields: (46/90) + (39/90) = 85/90 = 17/18

11. 1/4 + 0.5: Converting 0.5 to a fraction gives us 1/2. Now we can add the fractions: 1/4 + 1/2 = 1/4 + 2/4 = 3/4

12. 3/4
