Answer 1

1)3 2/5-3/5+5 4/5=8 3/5
2)8 7/9-3 4/9+5 8/9= 10  11/9=11 2/9
3) 25 13/40-(24 13/40+19/40)=25  13/40-24 32/40=21/40

4) 24 9/11+8 7/11)-24 9/11=32 16/11-24  9/11=8 7/11

5) (4 17/30+52 29/30)-50 29/30=56  46/30-50 29/30=6 17/30

6) (4-1 2/7-)-(6/7+1 1/7)=2 5/7-2=5/7

7) (12 1/8-4 5/8+0)-6 7/8=7 4/8-6 7/8=5/8

8) (1 3/17+5 16/17)+(1 1/17+2 14/17)-5 12/17=6 19/17+3 15/17-5 12/17=5 5/17

Answer 2

Solving the Fraction Problems

Let's solve the given fraction problems step by step.

1) 3 2/5 - 3/5 + 5 4/5: - First, convert all the mixed numbers to improper fractions. - Then perform the operations.

Solution: - 3 2/5 = 17/5 - 5 4/5 = 29/5

17/5 - 3/5 + 29/5 = (17 - 3 + 29)/5 = 43/5

Answer: 43/5

2) 8 7/9 - 3 + 4/9 + 5 8/9: - First, convert all the mixed numbers to improper fractions. - Then perform the operations.

Solution: - 8 7/9 = 79/9 - 5 8/9 = 53/9

79/9 - 3 + 4/9 + 53/9 = (79 - 27 + 4 + 53)/9 = 109/9

Answer: 109/9

3) 25 13/40 - (24 + 13/40 + 19/40) + 4: - First, simplify the expression inside the parentheses. - Then perform the operations.

Solution: - (24 + 13/40 + 19/40) = 24 + (13 + 19)/40 = 24 + 32/40 = 24 + 4/5 = 124/5

25 13/40 - 124/5 + 4 = (25 + 13/40) - 124/5 + 4 = (125/5 + 13/40) - 124/5 + 4 = (625/25 + 13/40) - 124/5 + 4 = (625 + 13)/25 - 124/5 + 4 = 638/25 - 124/5 + 4 = (638 - 620)/25 + 4 = 18/25 + 4 = 18/25 + 100/25 = 118/25

Answer: 118/25

4) 24 9/11 + 8 7/11 - 24 + 9/11 + 5: - First, convert all the mixed numbers to improper fractions. - Then perform the operations.

Solution: - 24 9/11 = 273/11 - 8 7/11 = 95/11

273/11 + 95/11 - 24 + 9/11 + 5 = (273 + 95 - 264 + 9 + 55)/11 = 168/11

Answer: 168/11

5) 4 17/30 + 52 29/30 - 50 + 29/30 + 6: - First, convert all the mixed numbers to improper fractions. - Then perform the operations.

Solution: - 4 17/30 = 137/30 - 52 29/30 = 1589/30

137/30 + 1589/30 - 50 + 29/30 + 6 = (137 + 1589 - 1500 + 29 + 180)/30 = 35/30

Answer: 35/30

6) 1 3/17 + 5 16/17: - First, convert all the mixed numbers to improper fractions. - Then perform the operations.

Solution: - 1 3/17 = 20/17 - 5 16/17 = 91/17

20/17 + 91/17 = (20 + 91)/17 = 111/17

Answer: 111/17

7) 1 1/17 + 2 14/17: - First, convert all the mixed numbers to improper fractions. - Then perform the operations.

Solution: - 1 1/17 = 18/17 - 2 14/17 = 48/17

18/17 + 48/17 = (18 + 48)/17 = 66/17

Answer: 66/17

8) 5 12/17: - This is already a mixed number.

Answer: 5 12/17
