When multiplying fractions, the numerators (top numbers) are multiplied together and put as the numerator over the denominators (bottom numbers) multiplied together.When adding fractions, they must both have the same denominator - the fractions are made into equivalent fractions with a common denominator; then the numerators are added together and put over the same common denominator.In both cases of multiplication and addition, the resulting fractions are reduced to simplest form.
