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!:)
