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.
The fraction: - 6/12
- The prime factorizations of the numerator and denominator:
- 6 = 2 × 3
- 12 = 22 × 3
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
- GCF (6; 12) = 2 × 3 = 6
- 6/12 = - (6 ÷ 6)/(12 ÷ 6) = - 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 6/12 = - (2 × 3)/(22 × 3) = - ((2 × 3) ÷ (2 × 3))/((22 × 3) ÷ (2 × 3)) = - 1/2
The fraction: - 8/16
- 8 = 23
- 16 = 24
- GCF (8; 16) = 23 = 8
- 8/16 = - (8 ÷ 8)/(16 ÷ 8) = - 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 8/16 = - 23/24 = - (23 ÷ 23)/(24 ÷ 23) = - 1/2
The fractions are equal.
This is one of the simplest cases when comparing two fractions.
Not only are the numerators of the fractions equal but their denominators are also equal.
