If the denominators are the same, add the numerators together and put that total over the same denominator. Reduce if possible. If the denominators are different...
1 Find the lowest common denominator, the bottom number (LCD)
2. Convert each fraction into an equivalent fraction whose denominator is the LCD
3. Add the numerator (the top number) of each fraction
4. Reduce the answer if possible
Example:
1/2 + 1/3
In this one 6 is the LCD, so you convert 1/2 to 3/6 and convert 1/3 to 2/6, then add the
numerator of each. You would then have 3/6 + 2/6 = 5/6
There are two methods to add fractions.
1. add in fraction form :
Take Least common multiple of denominators of both fractions, divide LCM by each denominator and multiply that factor to each numerator. Simply add both result numerators and the final result has the numerator as the sum of both numerators and resultant denominator is the LCM.
2. convert it to decimal and then add them:
Divide each numerator by its denominator and each will result in a decimal number. Now add both decimal number and that's the resultant answer in decimal form.

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.
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
How do you add fractions with unlike denomanators?
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.
Is it important to know how to add and subtract fractions why?
it is important to learn how to add and subtract fractions because we can use it when a time comes , when we have our own business and others .
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 is always needed to add fractions?
Fractions! Otherwise you don't have anything to add.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
How do I add improper fractions?
Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.
When you add fractions do you add the denominator to?
No.
When you add fractions do you flip improper fractions around?
no
What you need to add or subtract fractions?
You need a common denominator in order to add or subtract fractions.
How do you compare add fractions?
add by adding
How do you add unlike fractions?
Change them to like fractions and proceed.
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 the fractions?
with a calculator
Do you add denominators in fractions?
No.
