Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,751/29,999,999,988
- The integer number above the bar is called numerator: 16,666,666,751
- The integer number below the bar is called denominator: 29,999,999,988
- 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 = 16,666,666,751 ÷ 29,999,999,988
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:
16,666,666,751 = 7 × 2,380,952,393
16,666,666,751 is a composite number.
Written with exponents:
29,999,999,988 = 2 × 2 × 3 × 3 × 7 × 2,381 × 49,999 = 22 × 32 × 7 × 2,381 × 49,999
29,999,999,988 is a composite number.
16,666,666,751/29,999,999,988 =
(16,666,666,751 ÷ 7) / (29,999,999,988 ÷ 7) =
2,380,952,393/4,285,714,284
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.
16,666,666,751/29,999,999,988 =
(7 × 2,380,952,393)/(22 × 32 × 7 × 2,381 × 49,999) =
((7 × 2,380,952,393) ÷ 7) / ((22 × 32 × 7 × 2,381 × 49,999) ÷ 7) =
2,380,952,393/(22 × 32 × 2,381 × 49,999) =
2,380,952,393/4,285,714,284
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
2,380,952,393/4,285,714,284 =
2,380,952,393 ÷ 4,285,714,284 =
