Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,382/60,000,000,044
- The integer number above the bar is called numerator: 33,333,333,382
- The integer number below the bar is called denominator: 60,000,000,044
- 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 = 33,333,333,382 ÷ 60,000,000,044
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:
33,333,333,382 = 2 × 109 × 152,905,199
33,333,333,382 is a composite number.
Written with exponents:
60,000,000,044 = 2 × 2 × 109 × 137,614,679 = 22 × 109 × 137,614,679
60,000,000,044 is a composite number.
33,333,333,382/60,000,000,044 =
(33,333,333,382 ÷ 218) / (60,000,000,044 ÷ 218) =
152,905,199/275,229,358
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.
33,333,333,382/60,000,000,044 =
(2 × 109 × 152,905,199)/(22 × 109 × 137,614,679) =
((2 × 109 × 152,905,199) ÷ (2 × 109)) / ((22 × 109 × 137,614,679) ÷ (2 × 109)) =
152,905,199/(2 × 137,614,679) =
152,905,199/275,229,358
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
152,905,199/275,229,358 =
152,905,199 ÷ 275,229,358 =
