Adding unlike fractions?

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. Then add and simplify.


How can you find a common denominator for two unlike fractions?

Find the lowest common multiple of the denominators and adjust the fractions accordingly

What are the steps to subtract unlike fractions?

first find a common denominator then subtract the top numbers


What are some uses of the LCM?

We use the LCM to find the least common denominator of unlike fractions.


How do you find the least common denominator of a set of unlike fractions?

least common denominator is nothing but least common multiple of denominators.


Why can the least common multiple help you add fractions?

When adding unlike fractions, it is necessary to find a common denominator. The process of doing that is the same as finding an LCM.

How you use the least common multiple?

When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.


What is the use of LCM?

When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.


Why do you have to find a common denominator?

Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.


How do you add three fractions with unlike denominators?

-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.


How do you add or subtract dissimilar fractions?

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.


Is it always necessary to find the least common denominator to compare the sizes of fractions?

When comparing fractions you must find a common denominator; by finding the least common denominator it will keep the numbers (numerators and denominator) smaller .


How do you find a common denominator for fractions?

You do nowt


When you are multiplying fractions do you find the common denominator?

no


What must you find in order to add or subtract unlike fractions?

A common denominator. The best way is to find the LCM (Lowest Common Multiple) of all the denominators - the smallest number into which all the denominators will divide. (The easiest way to do this is to multiply all the different denominators together. Once this common denominator has been found, convert all the fractions into equivalent fractions with this new denominator.


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).


Which of the fractions is larger five sixths or seven twelfths?

To compare two fractions, find a common denominator, then convert each fraction to equivalent fractions with that common denominator. Finally, you compare the numerators. 5/6


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.


How can knowing the LCM help you add subtract and multiply fractions?

When adding and subtracting unlike fractions, it is necessary to find the LCM of the denominators, called the least common denominator. Once you have found the LCD, you can convert the fractions to equivalent fractions with a common denominator and proceed with the adding and/or subtracting. Finding an LCM will have no effect on multiplying fractions.


Where is a denominator used?

Many places, but a common one is in adding fractions where we find a common denominator.
