Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
36,295,115,518/300,000,000,004
- The integer number above the bar is called numerator: 36,295,115,518
- The integer number below the bar is called denominator: 300,000,000,004
- 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 = 36,295,115,518 ÷ 300,000,000,004
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:
36,295,115,518 = 2 × 31 × 79 × 7,410,191
36,295,115,518 is a composite number.
Written with exponents:
300,000,000,004 = 2 × 2 × 75,000,000,001 = 22 × 75,000,000,001
300,000,000,004 is a composite number.
36,295,115,518/300,000,000,004 =
(36,295,115,518 ÷ 2) / (300,000,000,004 ÷ 2) =
18,147,557,759/150,000,000,002
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.
36,295,115,518/300,000,000,004 =
(2 × 31 × 79 × 7,410,191)/(22 × 75,000,000,001) =
((2 × 31 × 79 × 7,410,191) ÷ 2) / ((22 × 75,000,000,001) ÷ 2) =
(31 × 79 × 7,410,191)/(2 × 75,000,000,001) =
18,147,557,759/150,000,000,002
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
18,147,557,759/150,000,000,002 =
18,147,557,759 ÷ 150,000,000,002 =
