Subtracting Fractions with unequal denominators is easy:
STEP 1: Find the lowest common factor between the denominator of all three fractions.
I.E.
4/8 - 2/9 (8 x 9 = 72).
Change the denominator to this number.
STEP 2: Ask yourself, what did you multiply the denominator of each fraction of to get the lowest common factor.
So, we multiplied 8 by 9 to get 72, and visa versa (9 by 8 to get 72).
So we would multiply the 4 by 9, and the 2 by 8.
Apply this to the algorithm.
(We now have 36/72 - 16/72)
STEP 3: Work out the algorithm as per normal.
(36/72 - 16/72 = 20/72)
STEP 4: Simplify your answer:
20/72 = 5/18

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 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 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.
How do you subtract fractions with unequal denominators?
by finding the common denominator of the fractions
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
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
What are the rules for subtracting fractions?
You multiply the fractions until the denominators are equal. Then, you subtract.
