Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,605/74,999,999,965
- The integer number above the bar is called numerator: 41,666,666,605
- The integer number below the bar is called denominator: 74,999,999,965
- 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 = 41,666,666,605 ÷ 74,999,999,965
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:
41,666,666,605 = 5 × 4,127 × 2,019,223
41,666,666,605 is a composite number.
74,999,999,965 = 5 × 11 × 1,363,636,363
74,999,999,965 is a composite number.
41,666,666,605/74,999,999,965 =
(41,666,666,605 ÷ 5) / (74,999,999,965 ÷ 5) =
8,333,333,321/14,999,999,993
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.
41,666,666,605/74,999,999,965 =
(5 × 4,127 × 2,019,223)/(5 × 11 × 1,363,636,363) =
((5 × 4,127 × 2,019,223) ÷ 5) / ((5 × 11 × 1,363,636,363) ÷ 5) =
(4,127 × 2,019,223)/(11 × 1,363,636,363) =
8,333,333,321/14,999,999,993
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,321/14,999,999,993 =
8,333,333,321 ÷ 14,999,999,993 =
0.555555554993 ≈
