Answer 2

The problem is
`21 (11)/(12) + 17 (5)/(12)`

Add the whole numbers


`21 + 17 = 38`

Match up the fractions and make sure the denominators are the same (they are)


`(11)/(12) + (5)/(12)`
`= (16)/(12)`

Break down the fraction


`16` ÷
`12 = 1 (4)/(12)`

Reduce-You need to find a common factor for both the numerator and denominator


`4` ÷
`4`
`= 1`


`12` ÷
`4 = 3`

Combine everything


`38 + 1(1)/(3) =39 (1)/(3)`

Answer:
`39 (1)/(3)`
