multiply the fractions until they have common denominators and then subtract them

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.

To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45−25 . Since the denominators are the same, subtract the numerators.

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.

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.

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.

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 to add fractions, the denominators must be equal.

you subtract the numerators, and leeave the denomonators alone

In fractions, you can NEVER add or subtract

You multiply the fractions until the denominators are equal. Then, you subtract.
