Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,342/60,000,000,034
- The integer number above the bar is called numerator: 33,333,333,342
- The integer number below the bar is called denominator: 60,000,000,034
- 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 = 33,333,333,342 ÷ 60,000,000,034
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:
33,333,333,342 = 2 × 3 × 5,555,555,557
33,333,333,342 is a composite number.
Written with exponents:
60,000,000,034 = 2 × 13 × 13 × 43 × 4,128,251 = 2 × 132 × 43 × 4,128,251
60,000,000,034 is a composite number.
33,333,333,342/60,000,000,034 =
(33,333,333,342 ÷ 2) / (60,000,000,034 ÷ 2) =
16,666,666,671/30,000,000,017
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.
33,333,333,342/60,000,000,034 =
(2 × 3 × 5,555,555,557)/(2 × 132 × 43 × 4,128,251) =
((2 × 3 × 5,555,555,557) ÷ 2) / ((2 × 132 × 43 × 4,128,251) ÷ 2) =
(3 × 5,555,555,557)/(132 × 43 × 4,128,251) =
16,666,666,671/30,000,000,017
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
16,666,666,671/30,000,000,017 =
16,666,666,671 ÷ 30,000,000,017 =
0.555555555385 ≈
