Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
4,444,444,434/6,666,666,666
- The integer number above the bar is called numerator: 4,444,444,434
- The integer number below the bar is called denominator: 6,666,666,666
- 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 = 4,444,444,434 ÷ 6,666,666,666
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:
4,444,444,434 = 2 × 3 × 740,740,739
4,444,444,434 is a composite number.
6,666,666,666 = 2 × 3 × 11 × 41 × 271 × 9,091
6,666,666,666 is a composite number.
4,444,444,434/6,666,666,666 =
(4,444,444,434 ÷ 6) / (6,666,666,666 ÷ 6) =
740,740,739/1,111,111,111
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.
4,444,444,434/6,666,666,666 =
(2 × 3 × 740,740,739)/(2 × 3 × 11 × 41 × 271 × 9,091) =
((2 × 3 × 740,740,739) ÷ (2 × 3)) / ((2 × 3 × 11 × 41 × 271 × 9,091) ÷ (2 × 3)) =
740,740,739/(11 × 41 × 271 × 9,091) =
740,740,739/1,111,111,111
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
740,740,739/1,111,111,111 =
740,740,739 ÷ 1,111,111,111 =
