Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
83,333,333,331/149,999,999,988
- The integer number above the bar is called numerator: 83,333,333,331
- The integer number below the bar is called denominator: 149,999,999,988
- 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 = 83,333,333,331 ÷ 149,999,999,988
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:
83,333,333,331 = 3 × 3 × 3 × 199 × 15,509,647 = 33 × 199 × 15,509,647
83,333,333,331 is a composite number.
Written with exponents:
149,999,999,988 = 2 × 2 × 3 × 12,499,999,999 = 22 × 3 × 12,499,999,999
149,999,999,988 is a composite number.
83,333,333,331/149,999,999,988 =
(83,333,333,331 ÷ 3) / (149,999,999,988 ÷ 3) =
27,777,777,777/49,999,999,996
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.
83,333,333,331/149,999,999,988 =
(33 × 199 × 15,509,647)/(22 × 3 × 12,499,999,999) =
((33 × 199 × 15,509,647) ÷ 3) / ((22 × 3 × 12,499,999,999) ÷ 3) =
(32 × 199 × 15,509,647)/(22 × 12,499,999,999) =
27,777,777,777/49,999,999,996
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
27,777,777,777/49,999,999,996 =
27,777,777,777 ÷ 49,999,999,996 =
