steps of explanation. Before adding or subtracting any two or three
fractions first we need to consider the denominator of the fractions. If
the denominators are same then we can put only one denominator and we
can add or subtract the numerator.Other wise if we have different
numbers in both denominators then we should take L.C.M of the fraction
and we need change them as same.Then we can add or subtract.For
multiplying two fractions we do not have to consider the denominators.We
can multiply numerator with numerator and denominator with denominator.
