Compare and sort in ascending order the two common ordinary fractions, which one is larger: ^{- 18}/₁₈ and ^{- 28}/₂₈. Common ordinary fractions compared and sorted in ascending order, result explained below

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

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.

- ¹⁸/₁₈ = - ^{(18 ÷ 18)}/_{(18 ÷ 18)} = - ¹/₁ = - 1

- ²⁸/₂₈ = - ^{(28 ÷ 28)}/_{(28 ÷ 28)} = - ¹/₁ = - 1

This is a simple case of comparing and sorting integer numbers.

The integer numbers are a particular case of those fractions that have a denominator equal to 1.

Any integer number 'n' can be written as a fraction with a denominator of 1. Starting from here, by multiplying both the numerator and the denominator by the same number, an integer number can be written as a multitude of equivalent fractions:

n = ⁿ/₁ = ^{(2 × n)}/₂ = ^{(3 × n)}/₃ = ...

Example: 3 = ³/₁ = ^{(2 × 3)}/₂ = ⁶/₂ = ^{(3 × 3)}/₃ = ⁹/₃ = ...

How are the numbers written: comma ',' used as a thousands separator; point '.' as a decimal separator; numbers rounded off to max. 12 decimals (if the case). Used symbols: '/' the fraction bar; ÷ dividing; × multiplying; + plus (adding); - minus (subtracting); = equal; ≈ approximately equal.
