Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
11,666,666,774/ - 38
Write the sign of the number in front of the fraction:
11,666,666,774/ - 38 = - 11,666,666,774/38
- The integer number above the bar is called numerator: 11,666,666,774
- The integer number below the bar is called denominator: 38
- 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 = - 11,666,666,774 ÷ 38
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:
11,666,666,774 = 2 × 7 × 833,333,341
11,666,666,774 is a composite number.
38 = 2 × 19
38 is a composite number.
- Prime number: a positive integer that is dividing evenly (without a remainder) only by itself and 1. A prime number has only two factors. Composite number: a positive integer that has at least one factor (divisor) other than 1 and itself.
2. Multiply all the common prime factors:
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
GCF (2 × 7 × 833,333,341; 2 × 19) = 2
Reduce (simplify) the common ordinary fraction: - 11,666,666,774/38
Divide the numerator and the denominator by their GCF.
- 11,666,666,774/38 =
- (11,666,666,774 ÷ 2) / (38 ÷ 2) =
- 5,833,333,387/19
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.
- 11,666,666,774/38 =
- (2 × 7 × 833,333,341)/(2 × 19) =
- ((2 × 7 × 833,333,341) ÷ 2) / ((2 × 19) ÷ 2) =
- (7 × 833,333,341)/19 =
- 5,833,333,387/19
- The fraction is now reduced to the lowest terms equivalent.
- The fraction is called irreducible and it has the smallest possible numerator and denominator.
- By reducing the values of the numerator and of the denominator of a fraction the calculations with that fraction are becoming easier to do.
The fraction - 5,833,333,387/19 is a negative improper fraction (|the numerator| > |the denominator|).
Rewrite the fraction
As a mixed number (also called a mixed fraction):
- A mixed number: a whole number and a proper fraction, both having the same sign.
- A proper fraction is a fraction in which the value of the numerator is less than the value of the denominator.
- Divide the numerator by the denominator and write down the quotient and the remainder of the division, as shown below:
- 5,833,333,387 ÷ 19 = - 307,017,546 and the remainder = - 13 ⇒
- 5,833,333,387 = - 307,017,546 × 19 - 13 ⇒
- 5,833,333,387/19 =
( - 307,017,546 × 19 - 13) / 19 =
- 307,017,546 - 13/19 =
- 307,017,546 13/19
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
- 307,017,546 13/19 =
- 307,017,546 - 13/19 =
- 307,017,546 - 13 ÷ 19 =
- 307,017,546.684210526316 ≈
- 307,017,546.68
As a percentage:
- A percentage value p% is equal to the fraction: p/100, for any decimal number p. So, we need to change the form of the number calculated above, to show a denominator of 100.
- To do that, multiply the number by the fraction 100/100.
- The value of the fraction 100/100 = 1, so by multiplying the number by this fraction the result is not changing, only the form.
- 307,017,546.684210526316 =
- 307,017,546.684210526316 × 100/100 =
- 30,701,754,668.421052631579/100 =
- 30,701,754,668.421052631579% ≈
- 30,701,754,668.42%
- In other words:
- (1) Calculate the fraction's value, (2) multiply that number by 100, and (3) add the percent sign % to it.
The final answer:
written in four ways
As a negative improper fraction:
(|the numerator| > |the denominator|):
11,666,666,774/ - 38 = - 5,833,333,387/19
As a mixed number:
(a whole number and a proper fraction having the same sign)
11,666,666,774/ - 38 = - 307,017,546 13/19
As a decimal number:
11,666,666,774/ - 38 ≈ - 307,017,546.68
