It is: 12
What would be the ideal Common Denominator for 2 and 4?
It is 12.
It is: 12
lcd(4, 6) = 12.
LCM, or least common denominator, for 4, 6, and 12 is 24.
12
LCD(6, 4) = 12.
The common denominator will be the LCM of these numbers, which is 120.
12 (4 x 3 = 12, 6 x 2 = 12)
To find the common denominator of two fractions, you find the least common multiple of the denominators. The multiply the numerators by whatever you multiplied the denominator by to get an equivalent fraction. example: 1 + 2 = 10 3 4 12 the least common multiple of 3 and 4 is 12 so, 4 + 6 = 10 12 12 12 which can be reduced to the answer of 5 6
The easiest way to find a common denominator of two numbers is to multiply them. Therefore, one of the common denominators for 6 and 7 would be 42 (7 x 6). This method will not necessarily produce the lowest common denominator, but it will determine one. For example, multiplying 4 and 6 will give you 24 as a common denominator. However, the lowest common denominator for 4 and 6 is 12.
