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.

What are the rules for multiplying fractions?
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
Why are two fractions converted into like fractions?
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
How do you subtract improper fractions with different denominators?
It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).
When multiplying fractions you must multiply the numerators together and multiply the denominators together?
true
How do you find common denominators with dividing fractions?
When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.
