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: - 94/190
- The prime factorizations of the numerator and denominator:
- 94 = 2 × 47
- 190 = 2 × 5 × 19
- 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 (94; 190) = 2
- 94/190 = - (94 ÷ 2)/(190 ÷ 2) = - 47/95
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 94/190 = - (2 × 47)/(2 × 5 × 19) = - ((2 × 47) ÷ 2)/((2 × 5 × 19) ÷ 2) = - 47/95
The fraction: - 96/192
- 96 = 25 × 3
- 192 = 26 × 3
- GCF (96; 192) = 25 × 3 = 96
- 96/192 = - (96 ÷ 96)/(192 ÷ 96) = - 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 96/192 = - (25 × 3)/(26 × 3) = - ((25 × 3) ÷ (25 × 3))/((26 × 3) ÷ (25 × 3)) = - 1/2
