Step-by-step explanation:
There are two ways to find the common denominator for two or more fractions. The first method involves finding the least common denominator, or the smallest whole number that's divisible by both denominators. To find the least common denominator, list the multiples of each denominator and then pick the smallest one.
Let's look at an example:
null
First, we'll find the multiples of each denominator.
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30. . .
The multiples of 7 are: 7, 14, 21, 28, 35, 42. . .
The smallest number that 3 and 7 have in common is 21. Therefore, 21 is the least common denominator.
The second method for finding the common denominator for two or more fractions is to multiply the denominators by each other.
Let's look at another example:
null
The denominators are 6 and 8. So, 6 * 8 = 48; therefore, 48 is the common denominator. While this method may appear easier, the common denominator may not be the least common denominator, meaning that at the end of the addition or subtraction problem, the fraction will have to be reduced to its simplest form.
