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: 40/20
- The prime factorizations of the numerator and denominator:
- 40 = 23 × 5
- 20 = 22 × 5
- 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 (40; 20) = 22 × 5 = 20
40/20 = (40 ÷ 20)/(20 ÷ 20) = 2/1 = 2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
40/20 = (23 × 5)/(22 × 5) = ((23 × 5) ÷ (22 × 5))/((22 × 5) ÷ (22 × 5)) = 2/1 = 2
The fraction: 46/23
- 46 = 2 × 23
- 23 is a prime number.
- GCF (46; 23) = 23
46/23 = (46 ÷ 23)/(23 ÷ 23) = 2/1 = 2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
46/23 = (2 × 23)/23 = ((2 × 23) ÷ 23)/(23 ÷ 23) = 2/1 = 2
The numbers are equal.
This is a simple case of comparing and sorting integer numbers.
The integer numbers are a particular case of those fractions that have a denominator equal to 1.
