Compare and sort in ascending order the two common ordinary fractions, which one is larger: - 26/13 and - 36/21. Common ordinary fractions compared and sorted in ascending order, result explained below
Compare: - 26/13 and - 36/21
To compare and sort multiple fractions, they should either have the same denominator or the same numerator.
The operation of comparing fractions:
- 26/13 and - 36/21
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.
- 26/13 = - (2 × 13)/13 = - ((2 × 13) ÷ 13)/(13 ÷ 13) = - 2/1 = - 2
- 36/21 = - (22 × 32)/(3 × 7) = - ((22 × 32) ÷ 3)/((3 × 7) ÷ 3) = - 12/7
To compare and sort the fractions, make their denominators the same.
Expand the fraction that has 1 as a denominator.
Multiply the numerator and denominator by the same number:
- 2 = - (7 × 2)/(7 × 1) = - 14/7
The fractions have the same denominator, compare their numerators.
The larger the numerator the smaller the negative fraction.
The larger the numerator the larger the positive fraction.
