Add. 7 2/15+ 5 2/3+ 9 13/15

A.21 2/3
B.20 2/3
C.22 2/3
D.21 10/15

Answer 1

`7 (2)/(15 ) + 5 (2)/(3) + 9 (3)/(15)`

Convert mixed number to improper fraction.


`(107)/(15) + (17)/(3) + (148)/(15)`

Then change all the denominators into a same number


`(107)/(15) + (85)/(15) + (148)/(15)`

Add all the numerators but let all the denominators be same.


`(107+85+148)/(15) = (340)/(15)`

Change the improper fraction back into a mixed number..


`22 (10)/(15)` I see that we can still simplify the fraction..


`22 (10)/(15) = 22 (2)/(3)`

Your final answer is C.
`22 (2)/(3)`
