Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
18,147,557,796/150,000,000,052
- The integer number above the bar is called numerator: 18,147,557,796
- The integer number below the bar is called denominator: 150,000,000,052
- 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 = 18,147,557,796 ÷ 150,000,000,052
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:
18,147,557,796 = 2 × 2 × 3 × 23 × 65,752,021 = 22 × 3 × 23 × 65,752,021
18,147,557,796 is a composite number.
Written with exponents:
150,000,000,052 = 2 × 2 × 7 × 5,357,142,859 = 22 × 7 × 5,357,142,859
150,000,000,052 is a composite number.
18,147,557,796/150,000,000,052 =
(18,147,557,796 ÷ 4) / (150,000,000,052 ÷ 4) =
4,536,889,449/37,500,000,013
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.
18,147,557,796/150,000,000,052 =
(22 × 3 × 23 × 65,752,021)/(22 × 7 × 5,357,142,859) =
((22 × 3 × 23 × 65,752,021) ÷ 22) / ((22 × 7 × 5,357,142,859) ÷ 22) =
(3 × 23 × 65,752,021)/(7 × 5,357,142,859) =
4,536,889,449/37,500,000,013
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
4,536,889,449/37,500,000,013 =
4,536,889,449 ÷ 37,500,000,013 =
