Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
536,363,636,374/900,000,000,020
- The integer number above the bar is called numerator: 536,363,636,374
- The integer number below the bar is called denominator: 900,000,000,020
- 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 = 536,363,636,374 ÷ 900,000,000,020
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:
536,363,636,374 = 2 × 29 × 601 × 811 × 18,973
536,363,636,374 is a composite number.
Written with exponents:
900,000,000,020 = 2 × 2 × 5 × 11 × 433 × 9,447,827 = 22 × 5 × 11 × 433 × 9,447,827
900,000,000,020 is a composite number.
536,363,636,374/900,000,000,020 =
(536,363,636,374 ÷ 2) / (900,000,000,020 ÷ 2) =
268,181,818,187/450,000,000,010
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.
536,363,636,374/900,000,000,020 =
(2 × 29 × 601 × 811 × 18,973)/(22 × 5 × 11 × 433 × 9,447,827) =
((2 × 29 × 601 × 811 × 18,973) ÷ 2) / ((22 × 5 × 11 × 433 × 9,447,827) ÷ 2) =
(29 × 601 × 811 × 18,973)/(2 × 5 × 11 × 433 × 9,447,827) =
268,181,818,187/450,000,000,010
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
268,181,818,187/450,000,000,010 =
268,181,818,187 ÷ 450,000,000,010 =
0.595959595958 ≈
