Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,650/74,999,999,942
- The integer number above the bar is called numerator: 41,666,666,650
- The integer number below the bar is called denominator: 74,999,999,942
- 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 = 41,666,666,650 ÷ 74,999,999,942
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:
41,666,666,650 = 2 × 5 × 5 × 7 × 2,381 × 49,999 = 2 × 52 × 7 × 2,381 × 49,999
41,666,666,650 is a composite number.
74,999,999,942 = 2 × 7 × 19 × 157 × 1,795,891
74,999,999,942 is a composite number.
41,666,666,650/74,999,999,942 =
(41,666,666,650 ÷ 14) / (74,999,999,942 ÷ 14) =
2,976,190,475/5,357,142,853
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.
41,666,666,650/74,999,999,942 =
(2 × 52 × 7 × 2,381 × 49,999)/(2 × 7 × 19 × 157 × 1,795,891) =
((2 × 52 × 7 × 2,381 × 49,999) ÷ (2 × 7)) / ((2 × 7 × 19 × 157 × 1,795,891) ÷ (2 × 7)) =
(52 × 2,381 × 49,999)/(19 × 157 × 1,795,891) =
2,976,190,475/5,357,142,853
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
2,976,190,475/5,357,142,853 =
2,976,190,475 ÷ 5,357,142,853 =
