Question

Please add 1/4+5/8+13/24. I am struggling with this basic math problem. Please show me the work.

Answer 1

Her you need to find LCM of the denominators

1 5 13
---- + ---- + ---- LCM is 24 so we make all denominators 24 as follows
4 8 24

1*6 5*3 13*1 6 15 13 6 + 15 + 13 34
----- + ----- + ------ = ---- + ---- + ----- = ------------- = -----
4*6 8*3 24*1 24 24 24 24 24

Numerator and denominator have a common factor 2, so dividing both by 2 we get final ans as

17 5
= ---- or as a mixed no. 1 -----
12 12
