Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
366,666,682/3,000,000,008
- The integer number above the bar is called numerator: 366,666,682
- The integer number below the bar is called denominator: 3,000,000,008
- 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 = 366,666,682 ÷ 3,000,000,008
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:
366,666,682 = 2 × 183,333,341
366,666,682 is a composite number.
Written with exponents:
3,000,000,008 = 2 × 2 × 2 × 61 × 6,147,541 = 23 × 61 × 6,147,541
3,000,000,008 is a composite number.
366,666,682/3,000,000,008 =
(366,666,682 ÷ 2) / (3,000,000,008 ÷ 2) =
183,333,341/1,500,000,004
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.
366,666,682/3,000,000,008 =
(2 × 183,333,341)/(23 × 61 × 6,147,541) =
((2 × 183,333,341) ÷ 2) / ((23 × 61 × 6,147,541) ÷ 2) =
183,333,341/(22 × 61 × 6,147,541) =
183,333,341/1,500,000,004
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
183,333,341/1,500,000,004 =
183,333,341 ÷ 1,500,000,004 =
