Answer 2

1) 12 3/7 + 4 2/7 - 5 5/7 First, we need to convert all the mixed numbers to improper fractions: 12 3/7 = (7*12 + 3)/7 = 87/7 4 2/7 = (7*4 + 2)/7 = 30/7 5 5/7 = (7*5 + 5)/7 = 40/7

Now we can add and subtract the fractions: 87/7 + 30/7 - 40/7 = (87 + 30 - 40)/7 = 77/7 = 11 So, the answer is 11.

2) 7 3/17 + 8 2/17 - 1 6/17 Again, convert the mixed numbers to improper fractions: 7 3/17 = (17*7 + 3)/17 = 124/17 8 2/17 = (17*8 + 2)/17 = 138/17 1 6/17 = (17*1 + 6)/17 = 23/17

Now we can add and subtract the fractions: 124/17 + 138/17 - 23/17 = (124 + 138 - 23)/17 = 239/17 So, the answer is 239/17.

3) 5 5/10 - (4 3/10 + 2 - 1/10) First, simplify the expression inside the parentheses: 4 3/10 + 2 - 1/10 = 4 3/10 + 20/10 - 1/10 = 4 22/10 - 1/10 = 4 21/10

Now subtract the expression inside the parentheses from 5 5/10: 5 5/10 - 4 21/10 = (50 + 5 - 42)/10 = 13/10 So, the answer is 13/10.

4) 9 9/10 - (3 2/10 + 2 3/10) First, simplify the expression inside the parentheses: 3 2/10 + 2 3/10 = 3 2/10 + 23/10 = 3 25/10

Now subtract the expression inside the parentheses from 9 9/10: 9 9/10 - 3 25/10 = (90 + 9 - 32)/10 = 67/10 So, the answer is 67/10.
