Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
10,666,666,600/19,999,999,914
- The integer number above the bar is called numerator: 10,666,666,600
- The integer number below the bar is called denominator: 19,999,999,914
- 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 = 10,666,666,600 ÷ 19,999,999,914
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:
10,666,666,600 = 2 × 2 × 2 × 5 × 5 × 41 × 1,300,813 = 23 × 52 × 41 × 1,300,813
10,666,666,600 is a composite number.
19,999,999,914 = 2 × 3 × 3,333,333,319
19,999,999,914 is a composite number.
10,666,666,600/19,999,999,914 =
(10,666,666,600 ÷ 2) / (19,999,999,914 ÷ 2) =
5,333,333,300/9,999,999,957
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.
10,666,666,600/19,999,999,914 =
(23 × 52 × 41 × 1,300,813)/(2 × 3 × 3,333,333,319) =
((23 × 52 × 41 × 1,300,813) ÷ 2) / ((2 × 3 × 3,333,333,319) ÷ 2) =
(22 × 52 × 41 × 1,300,813)/(3 × 3,333,333,319) =
5,333,333,300/9,999,999,957
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
5,333,333,300/9,999,999,957 =
5,333,333,300 ÷ 9,999,999,957 =
