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.

no.
Add it
Add a positive number - fraction or integer - to the given fraction.
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.
You can add or subract other fractions to it, or reduce it.
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.
