Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
18,147,557,791/150,000,000,062
- The integer number above the bar is called numerator: 18,147,557,791
- The integer number below the bar is called denominator: 150,000,000,062
- 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 = 18,147,557,791 ÷ 150,000,000,062
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:
18,147,557,791 = 11 × 3,257 × 506,533
18,147,557,791 is a composite number.
Written with exponents:
150,000,000,062 = 2 × 11 × 11 × 79 × 251 × 31,259 = 2 × 112 × 79 × 251 × 31,259
150,000,000,062 is a composite number.
18,147,557,791/150,000,000,062 =
(18,147,557,791 ÷ 11) / (150,000,000,062 ÷ 11) =
1,649,777,981/13,636,363,642
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.
18,147,557,791/150,000,000,062 =
(11 × 3,257 × 506,533)/(2 × 112 × 79 × 251 × 31,259) =
((11 × 3,257 × 506,533) ÷ 11) / ((2 × 112 × 79 × 251 × 31,259) ÷ 11) =
(3,257 × 506,533)/(2 × 11 × 79 × 251 × 31,259) =
1,649,777,981/13,636,363,642
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
1,649,777,981/13,636,363,642 =
1,649,777,981 ÷ 13,636,363,642 =
