How do you subtract improper fractions with different denominators?
It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).
How to add and subtract mixed numbers?
Convert them to improper fractions with common denominators and proceed.
How do you subtract mixed number to mixed number?
Convert them to improper fractions with common denominators and proceed normally.
What is least common multiple or LCM?
The LCM is used to help you add or subtract fractions with different denominators.
Why is it important to learn about equivalent fractions?
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
How do u subtract fractions?
multiply the fractions until they have common denominators and then subtract them
How do you subtract fractions without alike denominators?
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
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 add and subtract by fractions?
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
Why are two fractions converted into like fractions?
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
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.
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
How do you subtract fractions with same denominators?
you subtract the numerators, and leeave the denomonators alone
What are the rules for subtracting fractions?
You multiply the fractions until the denominators are equal. Then, you subtract.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
How are lcm's used in adding or subtracting fractions?
To add and subtract fractions, you need common denominators. To find the common denominator, take the LCM of the denominators you wish to add or subtract.
