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

To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.

415/110 = (5 × 83)/(2 × 5 × 11) = ((5 × 83) ÷ 5)/((2 × 5 × 11) ÷ 5) = 83/22


1,280/198 = (28 × 5)/(2 × 32 × 11) = ((28 × 5) ÷ 2)/((2 × 32 × 11) ÷ 2) = 640/99

1,179/178 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
1,179 = 32 × 131
178 = 2 × 89

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, which all have equal denominators

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:


22 = 2 × 11


99 = 32 × 11


178 = 2 × 89


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 (22, 99, 178) = 2 × 32 × 11 × 89 = 17,622


Calculate the expanding number of each fraction:

Divide the LCM by the denominator of each fraction.


83/22 : 17,622 ÷ 22 = (2 × 32 × 11 × 89) ÷ (2 × 11) = 801


640/99 : 17,622 ÷ 99 = (2 × 32 × 11 × 89) ÷ (32 × 11) = 178


1,179/178 : 17,622 ÷ 178 = (2 × 32 × 11 × 89) ÷ (2 × 89) = 99



Make the fractions' denominators the same:

Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated at the step 2, above.


This way all the fractions will have the same denominator:



83/22 = (801 × 83)/(801 × 22) = 66,483/17,622


640/99 = (178 × 640)/(178 × 99) = 113,920/17,622


1,179/178 = (99 × 1,179)/(99 × 178) = 116,721/17,622


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).
