Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,345/60,000,000,054
- The integer number above the bar is called numerator: 33,333,333,345
- The integer number below the bar is called denominator: 60,000,000,054
- 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 = 33,333,333,345 ÷ 60,000,000,054
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:
33,333,333,345 = 3 × 3 × 5 × 13 × 6,353 × 8,969 = 32 × 5 × 13 × 6,353 × 8,969
33,333,333,345 is a composite number.
60,000,000,054 = 2 × 3 × 33,889 × 295,081
60,000,000,054 is a composite number.
33,333,333,345/60,000,000,054 =
(33,333,333,345 ÷ 3) / (60,000,000,054 ÷ 3) =
11,111,111,115/20,000,000,018
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.
33,333,333,345/60,000,000,054 =
(32 × 5 × 13 × 6,353 × 8,969)/(2 × 3 × 33,889 × 295,081) =
((32 × 5 × 13 × 6,353 × 8,969) ÷ 3) / ((2 × 3 × 33,889 × 295,081) ÷ 3) =
(3 × 5 × 13 × 6,353 × 8,969)/(2 × 33,889 × 295,081) =
11,111,111,115/20,000,000,018
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
11,111,111,115/20,000,000,018 =
11,111,111,115 ÷ 20,000,000,018 =
