Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,292/60,000,000,078
- The integer number above the bar is called numerator: 33,333,333,292
- The integer number below the bar is called denominator: 60,000,000,078
- 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 = 33,333,333,292 ÷ 60,000,000,078
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:
33,333,333,292 = 2 × 2 × 7 × 7 × 73 × 2,329,699 = 22 × 72 × 73 × 2,329,699
33,333,333,292 is a composite number.
60,000,000,078 = 2 × 3 × 18,041 × 554,293
60,000,000,078 is a composite number.
33,333,333,292/60,000,000,078 =
(33,333,333,292 ÷ 2) / (60,000,000,078 ÷ 2) =
16,666,666,646/30,000,000,039
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.
33,333,333,292/60,000,000,078 =
(22 × 72 × 73 × 2,329,699)/(2 × 3 × 18,041 × 554,293) =
((22 × 72 × 73 × 2,329,699) ÷ 2) / ((2 × 3 × 18,041 × 554,293) ÷ 2) =
(2 × 72 × 73 × 2,329,699)/(3 × 18,041 × 554,293) =
16,666,666,646/30,000,000,039
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
16,666,666,646/30,000,000,039 =
16,666,666,646 ÷ 30,000,000,039 =
