Step 1
First of all, consider two general form of fractions.
Let the two fraction be ab and cd
Step 2
Now, to calculate the sum of the two numerators take the L.C.M of the denominators of two fractions.
Then rewrite the fraction as the equivalence fraction with the L.C.M of the denominators.
Add the numerators.
Summ of fractions= ab+cd
=adbd+bcbd (As L.C.M of b and d is bd)
=ad+bcbd

Step 3
Difference of fractions= ab+cd
=adbd+bcbd (As L.C.M of b and d is bd)
=ad+bcbd
