Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
81,666,666,632/350,000,002
- The integer number above the bar is called numerator: 81,666,666,632
- The integer number below the bar is called denominator: 350,000,002
- 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 = 81,666,666,632 ÷ 350,000,002
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:
81,666,666,632 = 2 × 2 × 2 × 113 × 90,339,233 = 23 × 113 × 90,339,233
81,666,666,632 is a composite number.
Written with exponents:
350,000,002 = 2 × 11 × 11 × 1,446,281 = 2 × 112 × 1,446,281
350,000,002 is a composite number.
- Exponential notation. 23 is the writing in exponential notation of the repeating multiplication: 2 × 2 × 2. Also: 23 is called the power. 2 is the base. 3 is the exponent. 8 is the value of the power: 23 = 8.
- 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 (23 × 113 × 90,339,233; 2 × 112 × 1,446,281) = 2
Reduce (simplify) the common ordinary fraction: 81,666,666,632/350,000,002
Divide the numerator and the denominator by their GCF.
81,666,666,632/350,000,002 =
(81,666,666,632 ÷ 2) / (350,000,002 ÷ 2) =
40,833,333,316/175,000,001
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.
81,666,666,632/350,000,002 =
(23 × 113 × 90,339,233)/(2 × 112 × 1,446,281) =
((23 × 113 × 90,339,233) ÷ 2) / ((2 × 112 × 1,446,281) ÷ 2) =
(22 × 113 × 90,339,233)/(112 × 1,446,281) =
40,833,333,316/175,000,001
- 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 40,833,333,316/175,000,001 is a positive 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:
40,833,333,316 ÷ 175,000,001 = 233 and the remainder = 58,333,083 ⇒
40,833,333,316 = 233 × 175,000,001 + 58,333,083 ⇒
40,833,333,316/175,000,001 =
(233 × 175,000,001 + 58,333,083) / 175,000,001 =
233 + 58,333,083/175,000,001 =
233 58,333,083/175,000,001
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
233 58,333,083/175,000,001 =
233 + 58,333,083/175,000,001 =
233 + 58,333,083 ÷ 175,000,001 =
233.333331900952 ≈
233.33
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.
233.333331900952 =
233.333331900952 × 100/100 =
23,333.333190095239/100 =
23,333.333190095239% ≈
23,333.33%
- 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 positive improper fraction:
