Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,662/75,000,000,018
- The integer number above the bar is called numerator: 41,666,666,662
- The integer number below the bar is called denominator: 75,000,000,018
- 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 = 41,666,666,662 ÷ 75,000,000,018
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:
41,666,666,662 = 2 × 37 × 479 × 1,175,497
41,666,666,662 is a composite number.
75,000,000,018 = 2 × 3 × 19 × 23 × 28,604,119
75,000,000,018 is a composite number.
41,666,666,662/75,000,000,018 =
(41,666,666,662 ÷ 2) / (75,000,000,018 ÷ 2) =
20,833,333,331/37,500,000,009
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.
41,666,666,662/75,000,000,018 =
(2 × 37 × 479 × 1,175,497)/(2 × 3 × 19 × 23 × 28,604,119) =
((2 × 37 × 479 × 1,175,497) ÷ 2) / ((2 × 3 × 19 × 23 × 28,604,119) ÷ 2) =
(37 × 479 × 1,175,497)/(3 × 19 × 23 × 28,604,119) =
20,833,333,331/37,500,000,009
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20,833,333,331/37,500,000,009 =
20,833,333,331 ÷ 37,500,000,009 =
