What else can I help you with?
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
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.
How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
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.

How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.

Why do you have to turn unlike fractions into like fractions to add or subtract?
because its just one of the rules of math :)

Do you always have to have like numerators in fractions before you can add or subtract?
No, the denominators have to be the same.
How would you add or subtract fractions with like denominators?
The same way you would add or subtract whole numbers, leaving the denominators alone.
To add and subtract fractions less than 1 you add or subtract only the what?
Numerators
Why is it necessary to convert two fractions into like fractions before adding and subtracting them?
Because think of like fractions as the same things.. you can subtract halves from halves for example, but what does it mean to take away a half from a third?By converting them into like fractions, we can add or subtract them easily.
Why do you need a common denominator with fractions?
You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.
