How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How do you subtract fractions in simplest form?
You first need to find a common denominator, not necessarily the least common denominator. Next, you rename the fractions according to the common denominator. Only then can you subtract the fractions. After subtraction you should simplify the answer.
When you subtract fractions do you subtract the denominator?
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
What are the steps to subtract unlike fractions?
first find a common denominator then subtract the top numbers
How do subtract two fractions with different denominator?
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators

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.
How do you subtract two fractions?
You have to find a common denominator, multiply them, subtract them and then simplify if you need to.
What are the steps to subtract unlike fractions?
first find a common denominator then subtract the top numbers
How do subtract two fractions with different denominator?
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators
How is finding the LCM revelant when adding and subtracting fractions?
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
Why do you need a common denominator?
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
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 subtract Fractions with models unlike denominators?
The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.
What part of the fraction does not change when you add or subtract?
If you find the common denominator for the fractions, then the bottom will stay the same :) BUT sometimes it is diffacult to find the common denominator so you may need help
