Compare the Two Common Fractions 5/6 and 10/12, Which One is Larger? Online Calculator

The operation of comparing fractions:
5/6 and 10/12

Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:


The fraction: 5/6

5/6 is already reduced to the lowest terms.

The numerator and denominator have no common prime factors:


  • 5 is a prime number.
  • 6 = 2 × 3
  • GCF (5; 6) = 1


The fraction: 10/12

  • The prime factorizations of the numerator and denominator:
  • 10 = 2 × 5
  • 12 = 22 × 3
  • Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
  • GCF (10; 12) = 2

10/12 = (10 ÷ 2)/(12 ÷ 2) = 5/6


The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:


10/12 = (2 × 5)/(22 × 3) = ((2 × 5) ÷ 2)/((22 × 3) ÷ 2) = 5/6




The fractions are equal.

This is one of the simplest cases when comparing two fractions.

Not only are the numerators of the fractions equal but their denominators are also equal.

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).
