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.
20/15 = (22 × 5)/(3 × 5) = ((22 × 5) ÷ 5)/((3 × 5) ÷ 5) = 4/3
30/18 = (2 × 3 × 5)/(2 × 32) = ((2 × 3 × 5) ÷ (2 × 3))/((2 × 32) ÷ (2 × 3)) = 5/3
The fractions have the same denominator, compare their numerators.
This is one of the simplest cases when comparing two fractions.
The larger the numerator the larger the positive fraction.
The larger the numerator the smaller the negative fraction.
