Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
18,147,557,775/150,000,000,027
- The integer number above the bar is called numerator: 18,147,557,775
- The integer number below the bar is called denominator: 150,000,000,027
- 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 = 18,147,557,775 ÷ 150,000,000,027
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:
18,147,557,775 = 3 × 5 × 5 × 59 × 1,721 × 2,383 = 3 × 52 × 59 × 1,721 × 2,383
18,147,557,775 is a composite number.
150,000,000,027 = 3 × 881 × 56,753,689
150,000,000,027 is a composite number.
18,147,557,775/150,000,000,027 =
(18,147,557,775 ÷ 3) / (150,000,000,027 ÷ 3) =
6,049,185,925/50,000,000,009
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.
18,147,557,775/150,000,000,027 =
(3 × 52 × 59 × 1,721 × 2,383)/(3 × 881 × 56,753,689) =
((3 × 52 × 59 × 1,721 × 2,383) ÷ 3) / ((3 × 881 × 56,753,689) ÷ 3) =
(52 × 59 × 1,721 × 2,383)/(881 × 56,753,689) =
6,049,185,925/50,000,000,009
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
6,049,185,925/50,000,000,009 =
6,049,185,925 ÷ 50,000,000,009 =
