Answer:
1/2 + 2/3 = 3/6 + 4/6 = 7/6
4/3 + 6/2 = 12/9 + 12/4 = 13/3
Explanation:
In a fraction, a numerator is a number that is been divided and a denominator is a number that divides. Common, in the context of division, is the lowest number that is a multiple of all the denominators/numerators, please see the two following examples:
1. Finding common denominator:
1/2 + 2/3 = 3/6 + 4/6 = 7/6
as you can see we express the sum of two fractions as the sum of the other two fractions with a common denominator. to do it you need to multiply the first fraction by 3/3 and the second one by 2/2.
2. Finding common numerator:
4/3 + 6/2 = 12/9 + 12/4 = 13/3
as you can see we express the sum of two fractions as the sum of the other two fractions with a common numerator. to do it you need to multiply the first fraction by 3/3 and the second one by 2/2.
