Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
166,666,660/1,499,999,982
- The integer number above the bar is called numerator: 166,666,660
- The integer number below the bar is called denominator: 1,499,999,982
- 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 = 166,666,660 ÷ 1,499,999,982
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:
166,666,660 = 2 × 2 × 5 × 1,667 × 4,999 = 22 × 5 × 1,667 × 4,999
166,666,660 is a composite number.
1,499,999,982 = 2 × 3 × 13 × 331 × 58,099
1,499,999,982 is a composite number.
166,666,660/1,499,999,982 =
(166,666,660 ÷ 2) / (1,499,999,982 ÷ 2) =
83,333,330/749,999,991
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.
166,666,660/1,499,999,982 =
(22 × 5 × 1,667 × 4,999)/(2 × 3 × 13 × 331 × 58,099) =
((22 × 5 × 1,667 × 4,999) ÷ 2) / ((2 × 3 × 13 × 331 × 58,099) ÷ 2) =
(2 × 5 × 1,667 × 4,999)/(3 × 13 × 331 × 58,099) =
83,333,330/749,999,991
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
83,333,330/749,999,991 =
83,333,330 ÷ 749,999,991 =
0.111111108 ≈
