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.

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.

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.

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.

You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.

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.

Possible reasons: To add or subtract fractions, To compare fractions with different denominators.

YOU JUST CANT....go on you try it

by finding the common denominator of the fractions

2/6

Because to add fractions, the denominators must be equal.

Dissimilar fractions have different denominators.

you subtract the numerators, and leeave the denomonators alone

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

In fractions, you can NEVER add or subtract

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).

Whether the denominators are common or not.

The LCM is used to help you add or subtract fractions with different denominators.

Convert them to improper fractions and proceed.

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.

unlike 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.

The same way you would add or subtract whole numbers, leaving the denominators alone.
