To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.

For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).

To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:

5/40 + 4/40
