Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,330/60,000,000,035
- The integer number above the bar is called numerator: 33,333,333,330
- The integer number below the bar is called denominator: 60,000,000,035
- 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 = 33,333,333,330 ÷ 60,000,000,035
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:
33,333,333,330 = 2 × 3 × 5 × 11 × 41 × 271 × 9,091
33,333,333,330 is a composite number.
60,000,000,035 = 5 × 41 × 292,682,927
60,000,000,035 is a composite number.
33,333,333,330/60,000,000,035 =
(33,333,333,330 ÷ 205) / (60,000,000,035 ÷ 205) =
162,601,626/292,682,927
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.
33,333,333,330/60,000,000,035 =
(2 × 3 × 5 × 11 × 41 × 271 × 9,091)/(5 × 41 × 292,682,927) =
((2 × 3 × 5 × 11 × 41 × 271 × 9,091) ÷ (5 × 41)) / ((5 × 41 × 292,682,927) ÷ (5 × 41)) =
(2 × 3 × 11 × 271 × 9,091)/292,682,927 =
162,601,626/292,682,927
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
162,601,626/292,682,927 =
162,601,626 ÷ 292,682,927 =
0.555555555176 ≈
