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: 22/22
22/22 = (22 ÷ 22)/(22 ÷ 22) = 1/1 = 1
The fraction: 30/27
- The prime factorizations of the numerator and denominator:
- 30 = 2 × 3 × 5
- 27 = 33
- 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 (30; 27) = 3
30/27 = (30 ÷ 3)/(27 ÷ 3) = 10/9
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
30/27 = (2 × 3 × 5)/33 = ((2 × 3 × 5) ÷ 3)/(33 ÷ 3) = 10/9
