Frequently asked
How do you multiply fractions?
Multiply the two numerators to get the new top number, multiply the two denominators to get the new bottom number, then simplify the result.
Do I need a common denominator to multiply?
No. Common denominators are only needed for addition and subtraction. Multiplication goes straight across.
How do I multiply a fraction by a whole number?
Write the whole number as itself over 1 — for example 5 becomes 5/1 — then multiply across.
