A common denominator is 12.
The LCD for 3/4 and 1/2 is 4.
20 is the lowest common denominator for 4 and 10.
The least common denominator of 1/4 and 1/5 is 20.The LCD of 1/2 and 1/3 is 6.
LCD(3, 4) = 12
A common denominator is 12.
To find the least common denominator of 1/3 and 1/4, we need to determine the smallest multiple that both denominators (3 and 4) have in common. The least common denominator is the least common multiple (LCM) of the denominators. The LCM of 3 and 4 is 12, so the least common denominator of 1/3 and 1/4 is 12.
1/4 plus 1/3 is the same as 3/12 plus 4/12 = 7/12To add 1/3 and 1/4, we must establish a common denominator. In this case a common denominator is 4 times 3, or 12. Finding a lowest common denominator is often a good idea but 12 already is the lowest common denominator. We convert both numbers (1/3 and 1/4) to have the common denominator by multiplying each by 1 (one) in the form to achieve the same denominator:1/3 * 4/4 = 4/121/4 * 3/3 = 3/12Now add the number together: 4/12 + 3/12 = 7/12 Since 7/12 can not be reduced, the final answer is 7/12.
1 * * * * * 60
The common denominator of any two or more whole numbers will always be 1.
The LCD for 3/4 and 1/2 is 4.
Well, darling, the common denominator for 1/3 and 4/9 is 9. You see, to add or subtract fractions, you need a common denominator, and in this case, multiplying 3 by 3 gives you 9. So, there you have it, simple math for a simple question.
20 is the lowest common denominator for 4 and 10.
You can use any common multiple of 2 and 4. The easiest (for subsequent calculations) to use is the lowest common multiple, which for 2 and 4 is 4. → 1/2 = 2/4 → 3/4 = 3/4 (it already has 4 in the denominator)
4.
The least common denominator of 1/4 and 1/5 is 20.The LCD of 1/2 and 1/3 is 6.
LCD(3, 4) = 12
