1. Make sure that the denominators (bottom number) are the same by finding the LCD. Ex: The LCD of 3 and 9 is 18 because 3x6=18 and 9x2=18.
2. Change the denominator's number to the new LCD. Ex: Before: 1/3 and 6/9. After: 1/18 and 6/18.
3. Line the fractions up and add the numerator(top number). Ex: 1+6=7.
4. Dont add the denominator!! It will still be the same!! So the examples' answer would be 7/18.
5. Usually, you simplify fractions but since 7 is an odd number, this fraction will remain the same.
Hope this helps!:)
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.
The fraction will increase.
Add it
add half the denominator to the numerator
1-a, which may or may not be a fraction.

Add a positive number - fraction or integer - to the given fraction.
no.
Add it
add half the denominator to the numerator
When you want to add it to another fraction.
1-a, which may or may not be a fraction.
The process is still that of addition.
You have to convert one of them to the other, and then add as usual.
To add a negative fraction to a mixed fraction, first convert the mixed fraction to an improper fraction. Then, find a common denominator for both fractions. Next, add the numerators and keep the common denominator. Finally, simplify the resulting fraction if needed. If the negative fraction has a smaller absolute value than the mixed fraction, you may need to borrow or regroup to ensure proper subtraction.
You can add or subract other fractions to it, or reduce it.
