RafaWell, honey, you don't multiply the denominator when multiplying fractions, you multiply the numerators together and then the denominators together. It's like a little math dance, you keep the bottom numbers separate and just focus on the tops. So, multiply those numerators like nobody's business and keep those denominators in their own little world.

When multiplying fractions when they have same common denominator do you multiply the denominators?
YES.
What do you do when you mutpiling fractions with common dennmonters?
Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.
Do you need a common denominator to divide fractions?
No. Dividing fractions is achieved by inverting the divisor and multiplying the resulting fractions. To multiply fractions the numerators are multiplied together to form the new numerator and the denominators are multiplied together to form the new denominator.
Division of fractions?
You can divide fractions by multiplying them by their reciprocal. You take the bottom fraction and turn it over, making the denominator the numerator. Once you have done this, you can simply multiply.
Do you need to change the denominator when multiplying fractions?
No.
