First, you find the least common denominator (list the denominators multiples and find the lowest one that they have in common). Then find out how many times you must multiply the denominators to get the LCD and multiply the numerators by the same number. Put these together to make a new fraction for each. Now you have to add the numerators together, make them one numerator, put the LCD as the denominator, and simplify this final fraction.
Example:
3/8 + 5/6 = ?
8, 16, 24, 32...
6, 12, 18, 24...
8x3=24, 3x3=9 3/8= 9/24
6x4=24, 5x4=20 5/6= 20/24
9+20=29, 9/24+20/24= 29/24= 1 5/24

How do you turn a fraction into a different fraction?
You can add or subract other fractions to it, or reduce it.

Never. You could write a fraction as a mixed fraction if you like and then the mixed fraction would have a different denominator (e.g.: 23/2 = 11 1/2)
How is adding mixed numbers different from adding fractions?
when you add mixed numbers you have a whole number but adding fraction does not.
What does finding the least common multiple have to do with finding different fraction chains to add to 1?
In general, the two are not related.
What will happen to a fraction if you add four to the denominator?
The fraction will increase.
How do you add a mixed fraction by a mixed fraction?
You can either add the fractional parts and, if required, convert the answer to a mixed fraction and then add the integer part to the integer parts of the two original numbers; or change both numbers to top-heavy (or improper) fractions, add them and then convert the answer to a mixed fraction.
Do you add the denominator in a fraction?
no.
How do you get a sum in a fraction?
Add it
How do you find a greater fraction?
Add a positive number - fraction or integer - to the given fraction.
Why if there are two fraction having different denominator are you are going to find first their least common denominator?
To get the right answer when you add or subtract them.
How do you add a half to a fraction?
add half the denominator to the numerator
When is an improper fraction best used?
When you want to add it to another fraction.
