First get their LCM.
LCM = 60

Rewrite the fractions with their LCD as denominators.
54/60 + 48/60 + 40/60

Add them all.
54/60 + 48/60 + 40/60 = 142/60

Get its lowest term.

9/10 + 4/5 + 8/12
FIND THE LCD
60 is the LCD.

60 / 10 x 9 = 54
60 / 5 x 4 = 48
60 / 12 x 8 = 40

54 + 48 + 40 = 142
142/60
Change to mixed number.
142/60 is 2. A remainder of 22. And still our denominator, 60.
Renaming, the answer is 
2 22/60
Rename more,
2 11/30
