Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
536,363,636,385/900,000,000,018
- The integer number above the bar is called numerator: 536,363,636,385
- The integer number below the bar is called denominator: 900,000,000,018
- 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 = 536,363,636,385 ÷ 900,000,000,018
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:
536,363,636,385 = 3 × 5 × 12,011 × 2,977,069
536,363,636,385 is a composite number.
Written with exponents:
900,000,000,018 = 2 × 3 × 3 × 3 × 7 × 1,543 × 1,543,067 = 2 × 33 × 7 × 1,543 × 1,543,067
900,000,000,018 is a composite number.
536,363,636,385/900,000,000,018 =
(536,363,636,385 ÷ 3) / (900,000,000,018 ÷ 3) =
178,787,878,795/300,000,000,006
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.
536,363,636,385/900,000,000,018 =
(3 × 5 × 12,011 × 2,977,069)/(2 × 33 × 7 × 1,543 × 1,543,067) =
((3 × 5 × 12,011 × 2,977,069) ÷ 3) / ((2 × 33 × 7 × 1,543 × 1,543,067) ÷ 3) =
(5 × 12,011 × 2,977,069)/(2 × 32 × 7 × 1,543 × 1,543,067) =
178,787,878,795/300,000,000,006
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
178,787,878,795/300,000,000,006 =
178,787,878,795 ÷ 300,000,000,006 =
0.595959595971 ≈
