What is a common multiple of the denominators of two or more fractions?
a common denominator
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
How do you compare fractions without common denominators?
Make them into decimals. Make them into decimals.
Do you have to change the denominators when multiplying fractions?
No. 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.
How do you compare fractions that are not similar?
To compare fractions which are not similar, the fractions must be made similar by putting them over a common denominator. There are two similar ways of doing this:Find the lowest common multiple of the denominators. Multiply the first numerator by whatever number you multiply the first denominator by to get that multiple, and do the same with the second numerator and denominator. You can then compare the numerators.Multiply the first numerator by the second denominator, and the second numerator by the first denominator, and put both numerators over the product of the two denominators. You can then compare the numerators.
What is an common multiple of the denominators for two or more fractions?
Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
What is the least common denominator of two fractions?
The least common denominator is the least common multiple of the denominators of the fractions.
How are common denominator and common multiple alike?
Common denominators are common multiples of two or more denominators.
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
A common multiple of the denominators of two or more fractions?
the common denominator!
What is a common multiple of the denominators of two or more fractions?
a common denominator
What is the blank is the least common multiple of the denominators of the fractions?
It is the LCD.

Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
How are a common denominator and common multiple different?
Common denominators are common multiples that are being used as denominators.
What is the LCD for fractions?
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
How do we add fractions in lowest terms?
You convert them to equivalent fractions each of whose denominators are the same - either the lowest common multiple (LCM) of the original denominators or a multiple of the LCM.
