For example 1 1/2 1 2/3 and 1 and 3/4 So first, let's rewrite them not as mixed numbers 3/2, 5/3 7/4 Now a common denominator is 12 So we rewrite them with 12 as the denominator 18/12, 20/12 and 21/12. Now ordering them is straightforward. The larger the numerator, the bigger the number.
A common denominator, though not the least one, is 24*21 = 504.
