Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
31,944,444,455/125,000,000,013
- The integer number above the bar is called numerator: 31,944,444,455
- The integer number below the bar is called denominator: 125,000,000,013
- 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 = 31,944,444,455 ÷ 125,000,000,013
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:
31,944,444,455 = 5 × 7 × 11 × 307 × 270,269
31,944,444,455 is a composite number.
125,000,000,013 = 3 × 7 × 5,952,380,953
125,000,000,013 is a composite number.
31,944,444,455/125,000,000,013 =
(31,944,444,455 ÷ 7) / (125,000,000,013 ÷ 7) =
4,563,492,065/17,857,142,859
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.
31,944,444,455/125,000,000,013 =
(5 × 7 × 11 × 307 × 270,269)/(3 × 7 × 5,952,380,953) =
((5 × 7 × 11 × 307 × 270,269) ÷ 7) / ((3 × 7 × 5,952,380,953) ÷ 7) =
(5 × 11 × 307 × 270,269)/(3 × 5,952,380,953) =
4,563,492,065/17,857,142,859
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
4,563,492,065/17,857,142,859 =
4,563,492,065 ÷ 17,857,142,859 =
