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: 19/122
19/122 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 19 is a prime number.
- 122 = 2 × 61
- GCF (19; 122) = 1
The fraction: 22/132
- The prime factorizations of the numerator and denominator:
- 22 = 2 × 11
- 132 = 22 × 3 × 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 (22; 132) = 2 × 11 = 22
22/132 = (22 ÷ 22)/(132 ÷ 22) = 1/6
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
22/132 = (2 × 11)/(22 × 3 × 11) = ((2 × 11) ÷ (2 × 11))/((22 × 3 × 11) ÷ (2 × 11)) = 1/6
