measure of value
Express all of them with a common denominator, then order them according to their numerators.
A common denominator is 7.A common denominator is 7.A common denominator is 7.A common denominator is 7.
A single number can not have a "common denominator", because a "common denominator" is a denominator which can be used to express both numbers. For example 1 / 2 and 1/3 have common denominators: 6, 12, 18, 24, 30, 36, etc... because you can express 1/2 as 3/6, 6/12, 9/18, 12/24, 15/30, 18/36 etc... and you can also express 1/3 as 2/6, 6/18, 8/24, 10/30, 12/36 etc... A non example is 9, which is NOT a common denominator of 1/2 and 1/3, because while you can express 1/3 as 3/9, 1/2 with a denominator of 9 would be 4.5/9, which is not a proper fraction.
That's the least common denominator or LCD.
The least common denominator.
A few synonyms for common denominator are , common divisor, common measure, denominator, numerator
A common denominator of 20 and 30 is 600. This is NOT the least common denominator, though.
The greatest common denominator is infinite. The least common denominator is 45.
A common denominator, though not the least, is 80.
There can be no greatest common denominator. For supose x is the greatest common denominator. ie 24 divides x and 36 divides x. Then 2x is a common denominator and 2x > x so 2x is a greater common denominator than the greatest common denominator. That contradiction implies that there is no greatest common denominator.
You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.
A common denominator is 84.
