The numerator and denominator of a product of fractions are simply the products of the numerators and denominators respectively. That is,
a/b * c/d = (a*c)/(b*d).
The denominators can be the same or different - that is irrelevant.

How do you write fractions with common denominators?
multiply the denominators
What is the rule for multiplying fractions with like denamonators?
Multiply all numerators to get numerator of the product. Multiply all denominators to get denominator of the product. This is true whether the factors have like or unlike denominators.
What are the rules for subtracting fractions?
You multiply the fractions until the denominators are equal. Then, you subtract.
How do u subtract fractions?
multiply the fractions until they have common denominators and then subtract them
How to multilply fractions?
Multiply the numerators together then multiply the denominators. Reduce as needed.
How do you write fractions with common denominators?
multiply the denominators
How do you multiply fractions with uncommon denominators?
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
Do you find common denominators when you multiply fractions?
No.

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.
How you multiply fractions?
To multiply fractions, multiply the numerators by the numerators, and the denominators by the denominators, and then (if possible) simplify the resulting fraction. For example, 2/3 x 4/5 = 8/15

How do you divide fractions with un common denominators?
When dividing fractions, the denominators don't matter. Multiply the first fraction by the reciprocal of the second.
Can you multiply fractions that have a different demonminator?
Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.
