We can only add or subtract fractions if they have the same denominators
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
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.
In fractions, you can NEVER add or subtract
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.

Convert them to improper fractions and proceed.
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.
The same way you would add or subtract whole numbers, leaving the denominators alone.
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.
No, the denominators have to be the same.
No. You just have to change it so the denominators are the same, and then it's easy from there!
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
