Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,542/74,999,999,886
- The integer number above the bar is called numerator: 41,666,666,542
- The integer number below the bar is called denominator: 74,999,999,886
- 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 = 41,666,666,542 ÷ 74,999,999,886
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:
41,666,666,542 = 2 × 73 × 359 × 794,953
41,666,666,542 is a composite number.
74,999,999,886 = 2 × 3 × 7 × 1,785,714,283
74,999,999,886 is a composite number.
41,666,666,542/74,999,999,886 =
(41,666,666,542 ÷ 2) / (74,999,999,886 ÷ 2) =
20,833,333,271/37,499,999,943
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.
41,666,666,542/74,999,999,886 =
(2 × 73 × 359 × 794,953)/(2 × 3 × 7 × 1,785,714,283) =
((2 × 73 × 359 × 794,953) ÷ 2) / ((2 × 3 × 7 × 1,785,714,283) ÷ 2) =
(73 × 359 × 794,953)/(3 × 7 × 1,785,714,283) =
20,833,333,271/37,499,999,943
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20,833,333,271/37,499,999,943 =
20,833,333,271 ÷ 37,499,999,943 =
