Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
327,083,274/4,999,999,921
- The integer number above the bar is called numerator: 327,083,274
- The integer number below the bar is called denominator: 4,999,999,921
- 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 = 327,083,274 ÷ 4,999,999,921
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:
327,083,274 = 2 × 3 × 3 × 7 × 2,595,899 = 2 × 32 × 7 × 2,595,899
327,083,274 is a composite number.
4,999,999,921 = 7 × 37 × 19,305,019
4,999,999,921 is a composite number.
327,083,274/4,999,999,921 =
(327,083,274 ÷ 7) / (4,999,999,921 ÷ 7) =
46,726,182/714,285,703
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.
327,083,274/4,999,999,921 =
(2 × 32 × 7 × 2,595,899)/(7 × 37 × 19,305,019) =
((2 × 32 × 7 × 2,595,899) ÷ 7) / ((7 × 37 × 19,305,019) ÷ 7) =
(2 × 32 × 2,595,899)/(37 × 19,305,019) =
46,726,182/714,285,703
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
46,726,182/714,285,703 =
46,726,182 ÷ 714,285,703 =
