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.
When multiplying fractions do you also multiply the denominator?
I dont know
When multiplying fractions when they have same common denominator do you multiply the denominators?
YES.
Do you have to find the common denominator when you are multiplying fractions?
no. you can multiply straight across in fraction multiplication
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.

How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
When dividing fractions is a reciprocal used by multiplying?
Yes. One method for dividing fractions is to multiply the numerator fraction by the reciprocal of the denominator fraction.
Why don't you have to find a common denominator when multiplying fractions?
Multiplying fractions is quite different from adding them. You just multiply the numberators and the denominators separately. You can find the common denominator if you like, but in the end (after simplifying), you'll get the same result, and the additional work of finding the common denominator and converting the fractions turns out to be unnecessary. Try it out for some fractions!
What is a general rule for multiplying fractions and whole numbers?
A general rule for multiplying fractions: You shall not multiply the denominator by the whole number,only the numerator.Another rule is you shall make the whole number as a fraction by putting the whole number as the numerator and 1 as the denominator before multiplying it.
Do you have to have a common denominator when your multiplying?
no u dnt need to have a common denominator.. Just multiply both the denominator and numerator of the fractions u are working on and u will arrive at the answers
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.
How do you make fractions into equivalent fractions?
You multiply (or divide) the numerator and the denominator by the same number. For example, 1/2 is equivalent to 3/6, which you get by multiplying both parts (numerator and denominator) by 3.
