Answer:
=1/4+1/3+1/8
Taking LCM of the denominators 4,3,8
Multiples of 4: 4,8,12,16,21,24,28,32,36...
Multiples of 8: 8,16,24,32,40,48,56...
Multiples of 3: 3,6,9,12,15,18,21,24,27,30,33,36,39
Now the common multiple in all the three is 24 so LCM is 24
We have to make the denominators common by making them all as 24
Multiply and divide 1/4 by 6 as
1*6/4*6=6/24
Multiply and divide 1/3 by 8 as
1*8/3*8=8/24
Multiply and divide 1/8 by 3 as
1*3/8*3=3/24
Now add them together
=6/24+8/24+3/24
As the denominator is common we can write
=(6+8+3)/24
=17/24(Solution)
