What is ordering fractions?

These fractions are unit fractions: Each of them has the same numerator. You can see that as the denominator gets larger, the fraction gets smaller. To order fractions with like numerators, look at the denominators and compare them two at a time. The fraction with the smaller denominator is the larger fraction.

Subsequently, one may also ask, how can you order fractions from least to greatest?

We do this by first converting all terms into fractions, finding the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.

How do you know if a fraction is bigger than another?

Compare 2/3 and 3/5 and find out which fraction is bigger.
  1. First look at the denominators (the bottom numbers).
  2. Find a new number that both denominators go into:
  3. Now you have found a new denominator that is divisable by both numbers, you need to change the numerators (the top numbers).

How do you use a benchmark fraction?

Compare fractions using a benchmark fraction. Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole.
