Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
433,333,333,347/500,000,000,013
- The integer number above the bar is called numerator: 433,333,333,347
- The integer number below the bar is called denominator: 500,000,000,013
- 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 = 433,333,333,347 ÷ 500,000,000,013
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:
433,333,333,347 = 3 × 144,444,444,449
433,333,333,347 is a composite number.
Written with exponents:
500,000,000,013 = 3 × 3 × 3 × 28,211 × 656,429 = 33 × 28,211 × 656,429
500,000,000,013 is a composite number.
433,333,333,347/500,000,000,013 =
(433,333,333,347 ÷ 3) / (500,000,000,013 ÷ 3) =
144,444,444,449/166,666,666,671
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.
433,333,333,347/500,000,000,013 =
(3 × 144,444,444,449)/(33 × 28,211 × 656,429) =
((3 × 144,444,444,449) ÷ 3) / ((33 × 28,211 × 656,429) ÷ 3) =
144,444,444,449/(32 × 28,211 × 656,429) =
144,444,444,449/166,666,666,671
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
144,444,444,449/166,666,666,671 =
144,444,444,449 ÷ 166,666,666,671 =
0.866666666671 ≈
