Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
How do you simplify fractions into their lower terms?
Keep dividing the numerator and denominator by any common factor they have, until they have no common factor except ' 1 '.
How do you simplify 66 over 56?
