Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
13,157,894,748/50,000,000,010
- The integer number above the bar is called numerator: 13,157,894,748
- The integer number below the bar is called denominator: 50,000,000,010
- 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 = 13,157,894,748 ÷ 50,000,000,010
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:
13,157,894,748 = 2 × 2 × 3 × 1,096,491,229 = 22 × 3 × 1,096,491,229
13,157,894,748 is a composite number.
50,000,000,010 = 2 × 3 × 5 × 1,666,666,667
50,000,000,010 is a composite number.
13,157,894,748/50,000,000,010 =
(13,157,894,748 ÷ 6) / (50,000,000,010 ÷ 6) =
2,192,982,458/8,333,333,335
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.
13,157,894,748/50,000,000,010 =
(22 × 3 × 1,096,491,229)/(2 × 3 × 5 × 1,666,666,667) =
((22 × 3 × 1,096,491,229) ÷ (2 × 3)) / ((2 × 3 × 5 × 1,666,666,667) ÷ (2 × 3)) =
(2 × 1,096,491,229)/(5 × 1,666,666,667) =
2,192,982,458/8,333,333,335
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
2,192,982,458/8,333,333,335 =
2,192,982,458 ÷ 8,333,333,335 =
