Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,372/60,000,000,081
- The integer number above the bar is called numerator: 33,333,333,372
- The integer number below the bar is called denominator: 60,000,000,081
- 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 = 33,333,333,372 ÷ 60,000,000,081
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:
33,333,333,372 = 2 × 2 × 3 × 3 × 17 × 23 × 2,368,097 = 22 × 32 × 17 × 23 × 2,368,097
33,333,333,372 is a composite number.
60,000,000,081 = 3 × 7 × 1,637 × 1,745,353
60,000,000,081 is a composite number.
33,333,333,372/60,000,000,081 =
(33,333,333,372 ÷ 3) / (60,000,000,081 ÷ 3) =
11,111,111,124/20,000,000,027
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.
33,333,333,372/60,000,000,081 =
(22 × 32 × 17 × 23 × 2,368,097)/(3 × 7 × 1,637 × 1,745,353) =
((22 × 32 × 17 × 23 × 2,368,097) ÷ 3) / ((3 × 7 × 1,637 × 1,745,353) ÷ 3) =
(22 × 3 × 17 × 23 × 2,368,097)/(7 × 1,637 × 1,745,353) =
11,111,111,124/20,000,000,027
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
11,111,111,124/20,000,000,027 =
11,111,111,124 ÷ 20,000,000,027 =
