Compare and sort in ascending order the two ordinary fractions, which one is larger: 19/30 vs. 1/2. Ordinary fractions compared and sorted in ascending order, result explained below

The operation of comparing fractions:
19/30 vs. 1/2

Reduce (simplify) fractions to their lowest terms equivalents:

19/30 already reduced to the lowest terms;
the numerator and the denominator have no common prime factors:
19 is a prime number;
30 = 2 × 3 × 5;


1/2 already reduced to the lowest terms;
the numerator and the denominator have no common prime factors:
1 cannot be factored into other prime factors;
2 is a prime number;

To sort fractions, build them up to the same numerator.

Expand the fraction that has 1 as a numerator


Multiply the numerator and the denominator by the same number:


1/2 = (19 × 1)/(19 × 2) = 19/38;


The fractions have the same numerator, compare their denominators.

The larger the denominator the smaller the positive fraction.

The final answer:

The fractions sorted in ascending order:
19/38 < 19/30

The initial fractions in ascending order:
1/2 < 19/30

Compare and sort the fractions in ascending order:

How to compare two fractions?

1. Fractions that have different signs:

  • Any positive fraction is larger than any negative fraction:
  • ie: 4/25 > - 19/2

2. A proper and an improper fraction:

  • Any positive improper fraction is larger than any positive proper fraction:
  • ie: 44/25 > 1 > 19/200
  • Any negative improper fraction is smaller than any negative proper fraction:
  • ie: - 44/25 < -1 < - 19/200

3. Fractions that have both like numerators and denominators:

  • The fractions are equal:
  • ie: 89/50 = 89/50

4. Fractions that have unlike (different) numerators but like (equal) denominators.

  • Positive fractions: compare the numerators, the larger fraction is the one with the larger numerator:
  • ie: 24/25 > 19/25
  • Negative fractions: compare the numerators, the larger fraction is the one with the smaller numerator:
  • ie: - 19/25 < - 17/25

5. Fractions that have unlike (different) denominators but like (equal) numerators.

  • Positive fractions: compare the denominators, the larger fraction is the one with the smaller denominator:
  • ie: 24/25 > 24/26
  • Negative fractions: compare the denominators, the larger fraction is the one with the larger denominator:
  • ie: - 17/25 < - 17/29

6. Fractions that have different denominators and numerators (unlike denominators and numerators).
