Suppose you there are two fractions: 1/7 and 2/3. Let us find the common denominator of these fractions. It is equal to the product of their denominators, ie 7 * 3 = 21.
Here are the common denominator of the fraction. To do this, multiply the numerator by the denominator of the first fraction of the second, and the second fraction the numerator by the denominator of the first, and the denominators of the two fractions will be equal to 21. We obtain the following: 3/21 and 14/21.
Putting these fractions, which will result in aa fraction with a common denominator. To do this, add the numerators given fractions. In this case the denominator will remain the same. That is, we get: 3/21 + 14/21 = 17/21. 17/21, and will be the result of addition of 1/7 and 2/3.
