Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,600/74,999,999,966
- The integer number above the bar is called numerator: 41,666,666,600
- The integer number below the bar is called denominator: 74,999,999,966
- 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 = 41,666,666,600 ÷ 74,999,999,966
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:
41,666,666,600 = 2 × 2 × 2 × 5 × 5 × 13 × 23 × 641 × 1,087 = 23 × 52 × 13 × 23 × 641 × 1,087
41,666,666,600 is a composite number.
74,999,999,966 = 2 × 37,499,999,983
74,999,999,966 is a composite number.
41,666,666,600/74,999,999,966 =
(41,666,666,600 ÷ 2) / (74,999,999,966 ÷ 2) =
20,833,333,300/37,499,999,983
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.
41,666,666,600/74,999,999,966 =
(23 × 52 × 13 × 23 × 641 × 1,087)/(2 × 37,499,999,983) =
((23 × 52 × 13 × 23 × 641 × 1,087) ÷ 2) / ((2 × 37,499,999,983) ÷ 2) =
(22 × 52 × 13 × 23 × 641 × 1,087)/37,499,999,983 =
20,833,333,300/37,499,999,983
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20,833,333,300/37,499,999,983 =
20,833,333,300 ÷ 37,499,999,983 =
