Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
166,666,674/1,500,000,000
- The integer number above the bar is called numerator: 166,666,674
- The integer number below the bar is called denominator: 1,500,000,000
- 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 = 166,666,674 ÷ 1,500,000,000
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:
166,666,674 = 2 × 3 × 17 × 1,633,987
166,666,674 is a composite number.
Written with exponents:
1,500,000,000 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 = 28 × 3 × 59
1,500,000,000 is a composite number.
166,666,674/1,500,000,000 =
(166,666,674 ÷ 6) / (1,500,000,000 ÷ 6) =
27,777,779/250,000,000
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.
166,666,674/1,500,000,000 =
(2 × 3 × 17 × 1,633,987)/(28 × 3 × 59) =
((2 × 3 × 17 × 1,633,987) ÷ (2 × 3)) / ((28 × 3 × 59) ÷ (2 × 3)) =
(17 × 1,633,987)/(27 × 59) =
27,777,779/250,000,000
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
27,777,779/250,000,000 =
27,777,779 ÷ 250,000,000 =
