Adding and Subtracting Unlike Fractions 150 150 SchoolTutoring Academy

Adding and Subtracting Unlike Fractions

Fractions with different denominators are unlike fractions. They cannot be added or subtracted as they are.  They are to be converted to like fractions first which have common denominator. Then the new numerators are added or subtracted and the result is the sum of the numerators over the common denominator. There is a simple rule…

Adding and Subtracting Like Fractions

Fractions with same denominators are called like fractions. Like fractions can be added and subtracted very easily. Simply add or subtract the numerators to get the resultant numerator and write the result over the common denominator which would be same as that of the two fractions. If needed the final fraction can be reduced to…
