When adding fractions, the denominator must be the same so that you can add the numerators: 1/3 + 1/3 = 2/3. This can also be written as a multiplication problem: 2/1 (which is the same thing as saying 2) x 1/3 =2/3. In the case of multiplying fractions you would multiply the numerators and the denominators so 2x1 and 3x1.
