those two operations are addition and subtraction.
the fractions have different denominators
The numbers that produce recurring numbers are: 3,6,7,9,11,12,13.. Hope this has helped you...
The denominator is the bottom number in a fraction. Fractions like 1/3 and 1/4 have different numbers on the bottom. Those are unlike denominators.
First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
Convert them to improper fractions with common denominators and proceed.
If the denominators (bottom numbers) are not equal, making equivalent fractions of them so that the denominators are equal. With the denominators equal if the numerators (top numbers) are equal, then the fractions are equal.

By using least common denominators when adding and subtracting fraction you get small numbers which are easy to perform operations on. On the other hand if you deal with common denominators which are excessively large, then you will find that operations are harder to perform. The one disadvantage of using LCD is that they can occasionally be difficult to find.

multiply the numerators (top numbers) together then multiply the denominators (lower numbers) together

The same way you would add or subtract whole numbers, leaving the denominators alone.
When adding unlike fractions, find the LCM of the denominators and convert them to it.
