Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,692/29,999,999,958
- The integer number above the bar is called numerator: 16,666,666,692
- The integer number below the bar is called denominator: 29,999,999,958
- 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 = 16,666,666,692 ÷ 29,999,999,958
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:
16,666,666,692 = 2 × 2 × 3 × 13 × 127 × 841,241 = 22 × 3 × 13 × 127 × 841,241
16,666,666,692 is a composite number.
29,999,999,958 = 2 × 3 × 61 × 81,967,213
29,999,999,958 is a composite number.
16,666,666,692/29,999,999,958 =
(16,666,666,692 ÷ 6) / (29,999,999,958 ÷ 6) =
2,777,777,782/4,999,999,993
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.
16,666,666,692/29,999,999,958 =
(22 × 3 × 13 × 127 × 841,241)/(2 × 3 × 61 × 81,967,213) =
((22 × 3 × 13 × 127 × 841,241) ÷ (2 × 3)) / ((2 × 3 × 61 × 81,967,213) ÷ (2 × 3)) =
(2 × 13 × 127 × 841,241)/(61 × 81,967,213) =
2,777,777,782/4,999,999,993
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
2,777,777,782/4,999,999,993 =
2,777,777,782 ÷ 4,999,999,993 =
