Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,664/74,999,999,977
- The integer number above the bar is called numerator: 41,666,666,664
- The integer number below the bar is called denominator: 74,999,999,977
- 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 = 41,666,666,664 ÷ 74,999,999,977
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:
41,666,666,664 = 2 × 2 × 2 × 3 × 7 × 7 × 17 × 19 × 43 × 2,551 = 23 × 3 × 72 × 17 × 19 × 43 × 2,551
41,666,666,664 is a composite number.
74,999,999,977 = 7 × 10,714,285,711
74,999,999,977 is a composite number.
41,666,666,664/74,999,999,977 =
(41,666,666,664 ÷ 7) / (74,999,999,977 ÷ 7) =
5,952,380,952/10,714,285,711
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.
41,666,666,664/74,999,999,977 =
(23 × 3 × 72 × 17 × 19 × 43 × 2,551)/(7 × 10,714,285,711) =
((23 × 3 × 72 × 17 × 19 × 43 × 2,551) ÷ 7) / ((7 × 10,714,285,711) ÷ 7) =
(23 × 3 × 7 × 17 × 19 × 43 × 2,551)/10,714,285,711 =
5,952,380,952/10,714,285,711
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
5,952,380,952/10,714,285,711 =
5,952,380,952 ÷ 10,714,285,711 =
