LCD for 12 and 17 is 204 (12X17=204)
17/20 is larger than 4/5. To compare fractions, put them both in a common denominator. Here, you can multiply 4/5 by 4/4 (equality) to create the fraction 16/20. 17/20 > 16/20 You can create a common denominator for fractions (where one is not a factor of the other) by finding the Least Common Multiple : multiply their uncommon factors by their common factors. Here, 20 is already a multiple of 5.
The highest or greatest common denominator of any two or more whole numbers, such as 7 and 17, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
The Least Common Multiple (LCM) for 13 17 is 221.
The least common multiple of 17 , 63 , 119 = 1,071
seventeen over fifteen because the common denominator of 5 and 3 is 15 think about it like this: 4/5x3, 4x3=12, 5x3=15 1/3x5, 1x5=5, 3x5=15 so you get 12/15+5/15 see how they simplify back? then add the numerators and keep the denominator and you get 17/15 or 1 and 2/15
The LCD for 17 and 12 is 204
A common denominator, though not the least, is 1700.
You need at least two fractions to determine a least common denominator.
Their product. If that's 1/2 and 1/7, the LCD is 14.

Their product.
119
It is 85

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
