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.
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent 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.
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators.

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
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.
Finding the prime factorizations of the denominators will help you find the least common denominator. Converting to equivalent fractions with like denominators will allow you to subtract them successfully.
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).
multiply the fractions until they have common denominators and then subtract them
Possible reasons: To add or subtract fractions, To compare fractions with different denominators.
If the denominators (bottom numbers) are the same (eg. 11/6 - 7/6) you just subtract the numerators (top numbers) eg. 11-7=4 so 4/6. If the denominators are different you have to find equivalent fractions where the denominators are the same.
