Answer 3

Let's solve each of these arithmetic problems step by step:

5. 20 - 3 8/15 + 10 4/15: First, subtract the fractions: 8/15 - 4/15 = 4/15 Now, add the whole numbers and the fraction: 20 - 3 + 10 + 4/15 = 27 + 4/15

So, 20 - 3 8/15 + 10 4/15 = 27 4/15

6. 30 - 15 9/10 - 12 3/10: First, subtract the fractions: 9/10 - 3/10 = 6/10 = 3/5 Now, subtract the whole numbers and the fraction: 30 - 15 - 12 + 3/5 = 15 - 12 + 3/5 = 3 + 3/5

So, 30 - 15 9/10 - 12 3/10 = 3 3/5

7. 15 7/11 - 4 9/16 + 3 4/11: First, subtract the fractions: 7/11 - 9/16 = (716 - 911) / (11*16) = (112 - 99) / 176 = 13/176 Now, add the whole numbers and the fraction: 15 - 4 + 3 + 13/176 = 14 + 13/176

So, 15 7/11 - 4 9/16 + 3 4/11 = 14 13/176

8. 49 - 19 3/5 - 2 2/5: First, subtract the fractions: 3/5 - 2/5 = 1/5 Now, subtract the whole numbers and the fraction: 49 - 19 - 2 + 1/5 = 30 - 2 + 1/5 = 28 + 1/5

So, 49 - 19 3/5 - 2 2/5 = 28 1/5

9. 12 4/13 - 2 13/20 + 3 9/13: First, subtract the fractions: 4/13 - 13/20 = (804 - 1313) / (13*20) = (320 - 169) / 260 = 151/260 Now, add the whole numbers and the fraction: 12 - 2 + 3 + 151/260 = 13 + 151/260

So, 12 4/13 - 2 13/20 + 3 9/13 = 13 151/260

10. 29 11/17 - 4 6/24 + 10 6/17: First, simplify the fractions: 6/24 = 1/4 Now, subtract the whole numbers and the fraction: 29 - 4 + 10 + 1/4 = 35 + 1/4

So, 29 11/17 - 4 6/24 + 10 6/17 = 35 1/4
