Numerator
Fraction = -----------------

ADDITION OF THREE FRACTIONAL NUMBER
1) 4/12 + 5/24 + 3/36
4 5 3
------- + ------- + -------
12 24 36
LCM of given Denominators is 72, So
(4 x 6) + (5 x 3) + ( 3 x 2 )
= ------------------------------
72
24 + 15 + 6
= ------------------
72
45
= -------------- (Ans.)
72
