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: 93/93
93/93 = (93 ÷ 93)/(93 ÷ 93) = 1/1 = 1
The fraction: 102/98
- The prime factorizations of the numerator and denominator:
- 102 = 2 × 3 × 17
- 98 = 2 × 72
- 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 (102; 98) = 2
102/98 = (102 ÷ 2)/(98 ÷ 2) = 51/49
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
102/98 = (2 × 3 × 17)/(2 × 72) = ((2 × 3 × 17) ÷ 2)/((2 × 72) ÷ 2) = 51/49
