Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
166,666,635/1,499,999,991
- The integer number above the bar is called numerator: 166,666,635
- The integer number below the bar is called denominator: 1,499,999,991
- 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 = 166,666,635 ÷ 1,499,999,991
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:
166,666,635 = 3 × 3 × 5 × 3,703,703 = 32 × 5 × 3,703,703
166,666,635 is a composite number.
1,499,999,991 = 3 × 7 × 71,428,571
1,499,999,991 is a composite number.
166,666,635/1,499,999,991 =
(166,666,635 ÷ 3) / (1,499,999,991 ÷ 3) =
55,555,545/499,999,997
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.
166,666,635/1,499,999,991 =
(32 × 5 × 3,703,703)/(3 × 7 × 71,428,571) =
((32 × 5 × 3,703,703) ÷ 3) / ((3 × 7 × 71,428,571) ÷ 3) =
(3 × 5 × 3,703,703)/(7 × 71,428,571) =
55,555,545/499,999,997
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
55,555,545/499,999,997 =
55,555,545 ÷ 499,999,997 =
