Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
536,363,636,376/900,000,000,009
- The integer number above the bar is called numerator: 536,363,636,376
- The integer number below the bar is called denominator: 900,000,000,009
- 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 = 536,363,636,376 ÷ 900,000,000,009
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:
536,363,636,376 = 2 × 2 × 2 × 3 × 6,007 × 3,720,407 = 23 × 3 × 6,007 × 3,720,407
536,363,636,376 is a composite number.
Written with exponents:
900,000,000,009 = 3 × 3 × 11 × 11 × 23 × 4,093 × 8,779 = 32 × 112 × 23 × 4,093 × 8,779
900,000,000,009 is a composite number.
536,363,636,376/900,000,000,009 =
(536,363,636,376 ÷ 3) / (900,000,000,009 ÷ 3) =
178,787,878,792/300,000,000,003
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.
536,363,636,376/900,000,000,009 =
(23 × 3 × 6,007 × 3,720,407)/(32 × 112 × 23 × 4,093 × 8,779) =
((23 × 3 × 6,007 × 3,720,407) ÷ 3) / ((32 × 112 × 23 × 4,093 × 8,779) ÷ 3) =
(23 × 6,007 × 3,720,407)/(3 × 112 × 23 × 4,093 × 8,779) =
178,787,878,792/300,000,000,003
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
178,787,878,792/300,000,000,003 =
178,787,878,792 ÷ 300,000,000,003 =
0.595959595967 ≈
