Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
333,333,333,346/500,000,000,006
- The integer number above the bar is called numerator: 333,333,333,346
- The integer number below the bar is called denominator: 500,000,000,006
- 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 = 333,333,333,346 ÷ 500,000,000,006
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:
333,333,333,346 = 2 × 13 × 17 × 29 × 26,005,097
333,333,333,346 is a composite number.
500,000,000,006 = 2 × 13 × 19 × 1,012,145,749
500,000,000,006 is a composite number.
333,333,333,346/500,000,000,006 =
(333,333,333,346 ÷ 26) / (500,000,000,006 ÷ 26) =
12,820,512,821/19,230,769,231
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.
333,333,333,346/500,000,000,006 =
(2 × 13 × 17 × 29 × 26,005,097)/(2 × 13 × 19 × 1,012,145,749) =
((2 × 13 × 17 × 29 × 26,005,097) ÷ (2 × 13)) / ((2 × 13 × 19 × 1,012,145,749) ÷ (2 × 13)) =
(17 × 29 × 26,005,097)/(19 × 1,012,145,749) =
12,820,512,821/19,230,769,231
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
12,820,512,821/19,230,769,231 =
12,820,512,821 ÷ 19,230,769,231 =
