Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,300/60,000,000,014
- The integer number above the bar is called numerator: 33,333,333,300
- The integer number below the bar is called denominator: 60,000,000,014
- The fraction bar means that the numerator is divided by the denominator.
- To get the fraction's value divide the numerator by the denominator:
The value = 33,333,333,300 ÷ 60,000,000,014
To reduce a fraction to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF
To calculate the greatest common factor, GCF:
- 1. Factor the numerator and the denominator (into prime factors), build their prime factorizations.
- 2. Multiply all their common prime factors, taken by the lowest exponents.
1. Factor the numerator and the denominator:
To factor a number (into prime factors) - or, in other words, to break it down to prime factors - or, in other words, to build its prime factorization: find the prime numbers that multiply together to get that number.
The prime factorizations:
Written with exponents:
33,333,333,300 = 2 × 2 × 3 × 3 × 3 × 5 × 5 × 37 × 333,667 = 22 × 33 × 52 × 37 × 333,667
33,333,333,300 is a composite number.
60,000,000,014 = 2 × 37 × 810,810,811
60,000,000,014 is a composite number.
33,333,333,300/60,000,000,014 =
(33,333,333,300 ÷ 74) / (60,000,000,014 ÷ 74) =
450,450,450/810,810,811
Yet another method to reduce the fraction
To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
33,333,333,300/60,000,000,014 =
(22 × 33 × 52 × 37 × 333,667)/(2 × 37 × 810,810,811) =
((22 × 33 × 52 × 37 × 333,667) ÷ (2 × 37)) / ((2 × 37 × 810,810,811) ÷ (2 × 37)) =
(2 × 33 × 52 × 333,667)/810,810,811 =
450,450,450/810,810,811
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
450,450,450/810,810,811 =
450,450,450 ÷ 810,810,811 =
0.55555555487 ≈
