RULES FOR ADDITION OF FRACTION

Rules for Addition of Fraction 

Step.1) Convert the mixed fraction into an improper fraction

Step.2) Convert all the fractions into like fraction

Step.3) Add the numerators of the like fractions obtained in step 2.

Step.4) Write a fraction with the numbers obtained in step 3 as the numerator and the common denominator in step 2 as the denominator.

Step.5) Reduce the fraction obtained in step 4 to its simplest form. If it is an improper fraction express it as a mixed fraction.

                       Numerator of the first X (LCM of denominator ÷                          denominator of the first) + Numerator of the                              second X (LCM of denominator ÷ denominator of                                       the second)
