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: 115/110
- The prime factorizations of the numerator and denominator:
- 115 = 5 × 23
- 110 = 2 × 5 × 11
- 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 (115; 110) = 5
115/110 = (115 ÷ 5)/(110 ÷ 5) = 23/22
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
115/110 = (5 × 23)/(2 × 5 × 11) = ((5 × 23) ÷ 5)/((2 × 5 × 11) ÷ 5) = 23/22
The fraction: 118/118
118/118 = (118 ÷ 118)/(118 ÷ 118) = 1/1 = 1
