Find the LCM of the denominators.
Example 1: 1/4 + 2/3
The LCM of 3 and 4 is 12, so the common denominator is 12. Convert each fraction to 12ths and add.
Example 2: 1/8 + 5/6
The LCM of 6 and 8 is 24, so the common denominator is 24. Convert each fraction to 24ths and add.

Why are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
What are fraction that have same denominator called?
They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.
What are compatible numbers for fractions?
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
How do you add fractions with the same denominator with whole numbers?
First you add the fractions then add the whole numbers I'd you can you can reduce the fractions bye multiplying Hope you have fun!😺🐆💙💎💖🐾
When you add fractions do you have to find a common denominator?
Only if the denominators are different.
When you add fractions do they have to have the same denominator?
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
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 fractions without the same denominatior?
Find their least common denominator and convert them.
When you add fractions do you have to have the same denominator?
Yes.
How do you add fractions with same numerator?
if it has a denominator
When you add fractions are you supposed to have the same denominator?
Yes, you are.
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 with the same denominator?
numerators you add, denominators you leave it the same
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.
How is adding like fractions and adding unlike fractions the same?
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.
How are fractions under addition?
In order to add or subtract fractions, they must have the same denominator.
Does adding numerators and denominators work in fraction addition?
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
