You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.
* Step two: convert both fractions to equivalent fractions that have that denominator.

Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
How do you subtract whole numbers by fractions?
Simplify them.
What is the procedure for adding and subtraction fracions?
1) Convert the fractions to equivalent fractions, to ensure they have the same denominator. 2) Once they have the same denominator, just add or subtract the numerators. 3) As with most problems with fractions, check whether you can simplify the final result.
How do you subtract fractions with like denominators?
Subtract the numerators as we normally subtract them and then divide the resultant by the denominator. It's just simple like that.
When subtracting fractions does the bottom have to be the same?
Yes the bottom has to be the same when subtracting fractions. The bottom (or denominator) tells you what you're working with. You cannot subtract thirds from halves just as you cannot subtract oranges from tissues.
How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
How do you add or subtract dissimilar fractions with or without regrouping?
What is the answer for 8 1/3 - 5 2/6
How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.
What you need to add or subtract fractions?
You need a common denominator in order to add or subtract fractions.
What are the rules of the dissimilar fractions?
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
Meaning of adding of dissimilar fractions?
Dissimilar fractions have different denominators and their lowest common denominator must be found in order to add them up.
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,
What is a dissimilar fractions?
Dissimilar fractions are fractions that have different denominators.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
How do you add the dissimilar fraction?
You have to convert them to equivalent similar fractions (fractions with the same denominator) first.
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.
To add and subtract fractions less than 1 you add or subtract only the what?
Numerators
