Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
1,010,101,050/4,000,000,011
- The integer number above the bar is called numerator: 1,010,101,050
- The integer number below the bar is called denominator: 4,000,000,011
- 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 = 1,010,101,050 ÷ 4,000,000,011
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:
1,010,101,050 = 2 × 3 × 3 × 3 × 5 × 5 × 7 × 89 × 1,201 = 2 × 33 × 52 × 7 × 89 × 1,201
1,010,101,050 is a composite number.
4,000,000,011 = 3 × 7 × 9,829 × 19,379
4,000,000,011 is a composite number.
1,010,101,050/4,000,000,011 =
(1,010,101,050 ÷ 21) / (4,000,000,011 ÷ 21) =
48,100,050/190,476,191
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.
1,010,101,050/4,000,000,011 =
(2 × 33 × 52 × 7 × 89 × 1,201)/(3 × 7 × 9,829 × 19,379) =
((2 × 33 × 52 × 7 × 89 × 1,201) ÷ (3 × 7)) / ((3 × 7 × 9,829 × 19,379) ÷ (3 × 7)) =
(2 × 32 × 52 × 89 × 1,201)/(9,829 × 19,379) =
48,100,050/190,476,191
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
48,100,050/190,476,191 =
48,100,050 ÷ 190,476,191 =
