Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
- 10/9,344
Write the sign of the number in front of the fraction:
- 10/9,344 = - 10/9,344
- The integer number above the bar is called numerator: 10
- The integer number below the bar is called denominator: 9,344
- The sign of the fraction: - (a negative value).
- 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 = - 10 ÷ 9,344
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:
10 = 2 × 5
10 is a composite number.
Written with exponents:
9,344 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 73 = 27 × 73
9,344 is a composite number.
- 10/9,344 =
- (10 ÷ 2) / (9,344 ÷ 2) =
- 5/4,672
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.
- 10/9,344 =
- (2 × 5)/(27 × 73) =
- ((2 × 5) ÷ 2) / ((27 × 73) ÷ 2) =
- 5/(26 × 73) =
- 5/4,672
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
- 5/4,672 =
- 5 ÷ 4,672 =
- 0.001070205479 ≈
