Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
18,147,557,880/150,000,000,069
- The integer number above the bar is called numerator: 18,147,557,880
- The integer number below the bar is called denominator: 150,000,000,069
- 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 = 18,147,557,880 ÷ 150,000,000,069
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:
18,147,557,880 = 2 × 2 × 2 × 3 × 3 × 5 × 50,409,883 = 23 × 32 × 5 × 50,409,883
18,147,557,880 is a composite number.
150,000,000,069 = 3 × 50,000,000,023
150,000,000,069 is a composite number.
18,147,557,880/150,000,000,069 =
(18,147,557,880 ÷ 3) / (150,000,000,069 ÷ 3) =
6,049,185,960/50,000,000,023
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.
18,147,557,880/150,000,000,069 =
(23 × 32 × 5 × 50,409,883)/(3 × 50,000,000,023) =
((23 × 32 × 5 × 50,409,883) ÷ 3) / ((3 × 50,000,000,023) ÷ 3) =
(23 × 3 × 5 × 50,409,883)/50,000,000,023 =
6,049,185,960/50,000,000,023
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
6,049,185,960/50,000,000,023 =
6,049,185,960 ÷ 50,000,000,023 =
