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: 100/95
- The prime factorizations of the numerator and denominator:
- 100 = 22 × 52
- 95 = 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 (100; 95) = 5
100/95 = (100 ÷ 5)/(95 ÷ 5) = 20/19
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
100/95 = (22 × 52)/(5 × 19) = ((22 × 52) ÷ 5)/((5 × 19) ÷ 5) = 20/19
The fraction: 102/102
102/102 = (102 ÷ 102)/(102 ÷ 102) = 1/1 = 1
