Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
366,666,672/2,999,999,994
- The integer number above the bar is called numerator: 366,666,672
- The integer number below the bar is called denominator: 2,999,999,994
- 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 = 366,666,672 ÷ 2,999,999,994
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:
366,666,672 = 2 × 2 × 2 × 2 × 3 × 7,638,889 = 24 × 3 × 7,638,889
366,666,672 is a composite number.
2,999,999,994 = 2 × 3 × 691 × 723,589
2,999,999,994 is a composite number.
366,666,672/2,999,999,994 =
(366,666,672 ÷ 6) / (2,999,999,994 ÷ 6) =
61,111,112/499,999,999
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.
366,666,672/2,999,999,994 =
(24 × 3 × 7,638,889)/(2 × 3 × 691 × 723,589) =
((24 × 3 × 7,638,889) ÷ (2 × 3)) / ((2 × 3 × 691 × 723,589) ÷ (2 × 3)) =
(23 × 7,638,889)/(691 × 723,589) =
61,111,112/499,999,999
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
61,111,112/499,999,999 =
61,111,112 ÷ 499,999,999 =
