Question

abhi mai class seven mai hu but k did'nt understand how to do LCM.

Answer 1

First take an example like

2/2 and 4/2

then see that the denominator is 2 then simply write 2 ...

4+2/2 [4+2 because the numerator is 4 and 2 so we must add it]

so answer is 6/2 so if we will cut these then it will be 3

If....there is one bigger denominator and smaller then we will write the bigger one....in some cases...
