Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,643/74,999,999,985
- The integer number above the bar is called numerator: 41,666,666,643
- The integer number below the bar is called denominator: 74,999,999,985
- 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 = 41,666,666,643 ÷ 74,999,999,985
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:
41,666,666,643 = 3 × 3 × 7 × 661,375,661 = 32 × 7 × 661,375,661
41,666,666,643 is a composite number.
74,999,999,985 = 3 × 5 × 17 × 14,033 × 20,959
74,999,999,985 is a composite number.
41,666,666,643/74,999,999,985 =
(41,666,666,643 ÷ 3) / (74,999,999,985 ÷ 3) =
13,888,888,881/24,999,999,995
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.
41,666,666,643/74,999,999,985 =
(32 × 7 × 661,375,661)/(3 × 5 × 17 × 14,033 × 20,959) =
((32 × 7 × 661,375,661) ÷ 3) / ((3 × 5 × 17 × 14,033 × 20,959) ÷ 3) =
(3 × 7 × 661,375,661)/(5 × 17 × 14,033 × 20,959) =
13,888,888,881/24,999,999,995
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
13,888,888,881/24,999,999,995 =
13,888,888,881 ÷ 24,999,999,995 =
