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