Find the sum of 2 1/9 + (-2/9) + 3 5/9

O A. -5
OB. 5
O c. 52/3
OD. 5 4/9
OE. 5 5/9

Answer 1

D.
`5(4)/(9)`

Explanation:

1. Convert mixed numbers into improper fractions:

`2(1)/(9) =(19)/(9)`

`3(5)/(9) =(32)/(9)`

`(19)/(9) +(-(2)/(9) )+(32)/(9)`

2. Solve:

`(19)/(9) +(-(2)/(9) )+(32)/(9) = (19)/(9) -(2)/(9) +(32)/(9)`

`(17)/(9) +(32)/(9)`

`(49)/(9)`

9 can go into 49 five times, so there will be a whole number of 5. There is 4/9 left over, so the final answer is:

`5(4)/(9)`
