Multiplying Fractions
Grade 5 · Math · Fraction Operations · New Jersey, USA
Lesson Summary
Multiply fractions by multiplying the numerators together and the denominators together.
Explanation
Multiplying fractions is simpler than adding or subtracting them because you do not need a common denominator. Just multiply the two numerators to get the new numerator, and multiply the two denominators to get the new denominator. Then simplify your answer. When multiplying a whole number by a fraction, write the whole number as a fraction over 1 first.
