Addition of fractions

Like fractions are fractions with same denominators. While adding like fractions, we add the numerator directly and write the denominator only once as shown below.

1/7+ 5/7= (1+5)/7 = 6/7

Unlike fractions are fractions with different denominators.

In the case of unlike fractions, we take least common multiple for the denominators. The next step is to multiply the numerator as well as the denominator of the respective fractions with suitable numbers so as to make the denominators common. One such sum is done below for reference.

2/5 + 1/4 = (2x4)/(5x4) + (1x5)/(4x5) = (8+5)/20 = 13/20

SUBTRACTION OF FRACTIONS

While multiplying, if simplification is not possible as shown in the above two sums,  then the numerators are multiplied together and the denominators are multiplied together to get the resultant fraction.

Let us take some examples where simplification is possible.  In such sums, we reduce the fraction to the lowest form.
