After reducing 120,000,000,063/90,000,000,039, the simplified fraction is converted and written as a decimal number, as a percentage and as a mixed number
Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
120,000,000,063/90,000,000,039
- The integer number above the bar is called numerator: 120,000,000,063
- The integer number below the bar is called denominator: 90,000,000,039
- 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 = 120,000,000,063 ÷ 90,000,000,039
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:
120,000,000,063 = 3 × 19 × 1,721 × 1,223,279
120,000,000,063 is a composite number.
90,000,000,039 = 3 × 30,000,000,013
90,000,000,039 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 (3 × 19 × 1,721 × 1,223,279; 3 × 30,000,000,013) = 3
Reduce (simplify) the common ordinary fraction: 120,000,000,063/90,000,000,039
Divide the numerator and the denominator by their GCF.
120,000,000,063/90,000,000,039 =
(120,000,000,063 ÷ 3) / (90,000,000,039 ÷ 3) =
40,000,000,021/30,000,000,013
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.
120,000,000,063/90,000,000,039 =
(3 × 19 × 1,721 × 1,223,279)/(3 × 30,000,000,013) =
((3 × 19 × 1,721 × 1,223,279) ÷ 3) / ((3 × 30,000,000,013) ÷ 3) =
(19 × 1,721 × 1,223,279)/30,000,000,013 =
40,000,000,021/30,000,000,013
- 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 40,000,000,021/30,000,000,013 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:
40,000,000,021 ÷ 30,000,000,013 = 1 and the remainder = 10,000,000,008 ⇒
40,000,000,021 = 1 × 30,000,000,013 + 10,000,000,008 ⇒
40,000,000,021/30,000,000,013 =
(1 × 30,000,000,013 + 10,000,000,008) / 30,000,000,013 =
1 + 10,000,000,008/30,000,000,013 =
1 10,000,000,008/30,000,000,013
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
1 10,000,000,008/30,000,000,013 =
1 + 10,000,000,008/30,000,000,013 =
1 + 10,000,000,008 ÷ 30,000,000,013 =
1.333333333456 ≈
1.33
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.
1.333333333456 =
1.333333333456 × 100/100 =
133.333333345556/100 =
133.333333345556% ≈
133.33%
- 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:
