Why do you have to multiply the denominators when multiplying fractions?

If you don't, how would you get a denominator? Also, think of it as, for example, 2/5 OF 5/10. 1/5 of 5/10 is 1/10 so 2/5 of 5/10 is 2/10 or 1/5. That's the concept behind the computation: 2/5 x 5/10=10/50. 10/50 divided by 10 is 1/5.

What are the rules for multiplying fractions?
When multiplying 2 fractions, we multiply the two numerators together and the two denominators together.
When multiplying fractions you must multiply the numerators together and multiply the denominators together?
true
How do you multiply a fraction?
Multiply the numerators together. Multiply the denominators together. Reduce, if possible. The answer when multiplying fractions together will always be lower than either.
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.
How do you write fractions with common denominators?
multiply the denominators

When multiplying fractions you must multiply the numerators together and multiply the denominators together?
true
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.
Why do you not use common denominators while multiplying fractions?
probably to multiply easier
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.
Do you change the denomanator if you multiply?
Yes, you multiply the numerators together and the denominators together when multiplying two fractions
When you multiply fractions why do you multiply the fractions strait across?
This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.

What are 3 steps you follow when multiplying fractions?
1. Multiply the numerators together. 2. Multiply the denominators together. 3. Simplify, if possible.
When multiplying fractions do you times the denominators if they are the same?
no you do not
