Compare and sort in ascending order the two common ordinary fractions, which one is larger: 43/33 and 50/41. Common ordinary fractions compared and sorted in ascending order, result explained below

Compare: 43/33 and 50/41

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

The operation of comparing fractions:
43/33 and 50/41

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

By reducing the values of the numerators and denominators of the fractions, further calculations with these fractions become easier to do.


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

43/33 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
43 is a prime number.
33 = 3 × 11

50/41 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
50 = 2 × 52
41 is a prime number.

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) then make their denominators the same by expanding 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.


The LCM will be the common denominator of the compared fractions.


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


33 = 3 × 11


41 is a prime number.


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 (33, 41) = 3 × 11 × 41 = 1,353


Calculate the expanding number of each fraction:

Divide the LCM by the denominator of each fraction.


43/33 : 1,353 ÷ 33 = (3 × 11 × 41) ÷ (3 × 11) = 41


50/41 : 1,353 ÷ 41 = (3 × 11 × 41) ÷ 41 = 33



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:



43/33 = (41 × 43)/(41 × 33) = 1,763/1,353


50/41 = (33 × 50)/(33 × 41) = 1,650/1,353


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).
