In addition of unlike fraction,we first find the LCM of the __________of the two fractions.
In addition of unlike fractions, we first find the LCM of the _denominators_ of the two fractions.
For example: 2/3 + 1/2:
LCM of denominators 3 and 2 is 6.
2/3=(2$ \times $2)/(2$ \times $3)=4/6
1/2=(1$ \times $3)/(2$ \times $3)=3/6
Therefore,
2/3+1/2=4/6+3/6=(4+3)/6=7/6
