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: - 98/94
- The prime factorizations of the numerator and denominator:
- 98 = 2 × 72
- 94 = 2 × 47
- 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 (98; 94) = 2
- 98/94 = - (98 ÷ 2)/(94 ÷ 2) = - 49/47
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 98/94 = - (2 × 72)/(2 × 47) = - ((2 × 72) ÷ 2)/((2 × 47) ÷ 2) = - 49/47
The fraction: - 100/100
- 100/100 = - (100 ÷ 100)/(100 ÷ 100) = - 1/1 = - 1
