Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,670/75,000,000,016
- The integer number above the bar is called numerator: 41,666,666,670
- The integer number below the bar is called denominator: 75,000,000,016
- 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 = 41,666,666,670 ÷ 75,000,000,016
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:
41,666,666,670 = 2 × 3 × 3 × 5 × 462,962,963 = 2 × 32 × 5 × 462,962,963
41,666,666,670 is a composite number.
Written with exponents:
75,000,000,016 = 2 × 2 × 2 × 2 × 4,687,500,001 = 24 × 4,687,500,001
75,000,000,016 is a composite number.
41,666,666,670/75,000,000,016 =
(41,666,666,670 ÷ 2) / (75,000,000,016 ÷ 2) =
20,833,333,335/37,500,000,008
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.
41,666,666,670/75,000,000,016 =
(2 × 32 × 5 × 462,962,963)/(24 × 4,687,500,001) =
((2 × 32 × 5 × 462,962,963) ÷ 2) / ((24 × 4,687,500,001) ÷ 2) =
(32 × 5 × 462,962,963)/(23 × 4,687,500,001) =
20,833,333,335/37,500,000,008
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20,833,333,335/37,500,000,008 =
20,833,333,335 ÷ 37,500,000,008 =
