Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,590/74,999,999,955
- The integer number above the bar is called numerator: 41,666,666,590
- The integer number below the bar is called denominator: 74,999,999,955
- 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 = 41,666,666,590 ÷ 74,999,999,955
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:
41,666,666,590 = 2 × 5 × 4,166,666,659
41,666,666,590 is a composite number.
74,999,999,955 = 3 × 5 × 29 × 139 × 1,240,387
74,999,999,955 is a composite number.
41,666,666,590/74,999,999,955 =
(41,666,666,590 ÷ 5) / (74,999,999,955 ÷ 5) =
8,333,333,318/14,999,999,991
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.
41,666,666,590/74,999,999,955 =
(2 × 5 × 4,166,666,659)/(3 × 5 × 29 × 139 × 1,240,387) =
((2 × 5 × 4,166,666,659) ÷ 5) / ((3 × 5 × 29 × 139 × 1,240,387) ÷ 5) =
(2 × 4,166,666,659)/(3 × 29 × 139 × 1,240,387) =
8,333,333,318/14,999,999,991
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,318/14,999,999,991 =
8,333,333,318 ÷ 14,999,999,991 =
