How do you get a common denominator for subtracting fractions?

Just multiply the two denominators of your fractions, the answer you get is a common denominator.

Do you multiply the common denominator in fractions?

you do not do that

How do you add improper fractions if the denominator can't multiply into the other denominator?

You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.

Do you need a common denominator to multiply fractions?


Do you need a common denominator for all fractions before doing the order of operations?

You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.

How to do inequality fractions?

It helps to find a common denominator and multiply both sides of the inequality by this common denominator. That way, you have an inequality without fractions.

When you multiply fractions do you multiply the denominator?

yes. you multiply the numerator and denominator

How do you multiply fractions with same denominator?

multiply denominator by denominator and vice versa

When multiplying fractions when they have same common denominator do you multiply the denominators?


Do you need to find a common denominator when you multiply fractions why or why not?


How can you find common denominator for two unlike fractions?

multiply the two denominators

How do you put different fractions in increasing order?

Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.

How do you change a fraction so they have the same denominator?

First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.

Do you multiply the denominator when you multiply fractions?

Yes you do.

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

How do you use comparing mixed fractions?

Assuming the fractions are "normalized" (the fractional part is less than 1): First compare the integer part. If the integer part is the same, you need to compare the fractions. If the denominator of the fractions is different, you have to convert to a common denominator. The simplest way to find a common denominator is to multiply both denominators (i.e., you don't need the LEAST common denominator - any common denominator will do).

How to add fractions having similar numerators but different denominators?

The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).

When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?

It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication. Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).

Why do you clear fractions in a linear equation?

Multiply every term in the equation by a common denominator of all the fractions. The least common denominator (if different) will result in smaller numbers that you then have to work with but it is not essential that you use it.

Do you have to find the common denominator when you are multiplying fractions?

no. you can multiply straight across in fraction multiplication

How do you subtract two fractions?

You have to find a common denominator, multiply them, subtract them and then simplify if you need to.

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!

How do you subtract and simplify fractions?

find a common denominator. multiply the top and bottom by it. then you can combine the numerators over the same denominator

How do you get the common denominator for dividing fractions?

You don't need a common denominator to divide fractions.

How do you make the denominator the same?

To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40
