Addition of Fractions with Different Denominators or Addition of Unlike Fractions involve following steps
Step 1 = LCM of Denominators of given Fraction
Step 2 = Divide LCM (obtained in step 1) with the denominators of given fractions.
Step 3 = Multiply quotient (obtained from step 2) with the numerators of given fractions.
For Example : Add the following fractions
2 7
+
3 5
LCM of denominators 7 and 5 = 35
Now, divide the LCM by denominator & multiply its quotient with numerators and we get:
{ (2 X 5) + (3 X 7) } 35
{10 + 21} 35
=
31 35
