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: 102/102
102/102 = (102 ÷ 102)/(102 ÷ 102) = 1/1 = 1
The fraction: 112/104
- The prime factorizations of the numerator and denominator:
- 112 = 24 × 7
- 104 = 23 × 13
- 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 (112; 104) = 23 = 8
112/104 = (112 ÷ 8)/(104 ÷ 8) = 14/13
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
112/104 = (24 × 7)/(23 × 13) = ((24 × 7) ÷ 23)/((23 × 13) ÷ 23) = 14/13
