all you have to do is follow the same algorithm for adding a pair of fractions together. the main step is to find common denominators between the two. to do this, you need to find the least common multiple. another way you could find a common denominator is just by changing them into decimals, and adding them normally like whole numbers with the decimals lined up correctly.

How do you subtract whole numbers by fractions?
Simplify them.
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 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.
How do you add or subtract dissimilar fractions?
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.
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 fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.
How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
How do u subtract fractions?
multiply the fractions until they have common denominators and then subtract them
How do you minnous fractions?
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.

What you need to add or subtract fractions?
You need a common denominator in order to add or subtract fractions.
How do you subtract bigger fractions from smaller fractions?
You don't
What you called when you subtract two fractions?
subtracting fractions
What does subtracting fractions mean?
It means you have to subtract fractions.
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.
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 subtract similar fractions?
Just subtract the numerators and copy the denominator
How do you subtract fractions with unequal denominators?
by finding the common denominator of the fractions
