Compare the Two Common Fractions 937/890 and 945/893, Which One is Larger? Online Calculator

Fractions 937/890 and 945/893 are compared by building equivalent fractions, which have either equal denominators or equal numerators

To compare and sort multiple fractions, they should either have the same denominator or the same numerator.

The operation of comparing fractions:
937/890 and 945/893

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


The fraction: 937/890

937/890 is already reduced to the lowest terms.

The numerator and denominator have no common prime factors:


  • 937 is a prime number.
  • 890 = 2 × 5 × 89
  • GCF (937; 890) = 1


The fraction: 945/893

945/893 is already reduced to the lowest terms.

The numerator and denominator have no common prime factors:


  • 945 = 33 × 5 × 7
  • 893 = 19 × 47
  • GCF (945; 893) = 1



To compare and sort the fractions, make their denominators the same.

To make the fractions' denominators the same - we have to:

  • 1) calculate their common denominator
  • 2) then calculate the expanding number of each fraction
  • 3) expand the fractions to equivalent forms having the same denominator

Calculate the common denominator

The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.


To calculate the LCM, we need the prime factorization of the denominators:

890 = 2 × 5 × 89

893 = 19 × 47


Multiply all the unique prime factors: if there are repeating prime factors we only take them once, and only the ones having the highest exponent (the highest powers).

LCM (890, 893) = 2 × 5 × 19 × 47 × 89 = 794,770



Calculate the expanding number of each fraction:

Divide the LCM by the denominator of each fraction.

937/890 ⟶ 794,770 ÷ 890 = (2 × 5 × 19 × 47 × 89) ÷ (2 × 5 × 89) = 893

945/893 ⟶ 794,770 ÷ 893 = (2 × 5 × 19 × 47 × 89) ÷ (19 × 47) = 890



Make the denominators of the fractions the same:

  • Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated above.
  • This way all the fractions will have the same denominator:

937/890 = (893 × 937)/(893 × 890) = 836,741/794,770

945/893 = (890 × 945)/(890 × 893) = 841,050/794,770



The fractions have the same denominator, compare their numerators.

The larger the numerator the larger the positive fraction.

The larger the numerator the smaller the negative fraction.

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).
