Detailed calculations below:
Fractions, brief introduction.
A fraction consists of two numbers and the fraction bar: 195/256,020
The number above the fraction bar is the numerator: 195
The number under the fraction bar is the denominator: 256,020
The fraction bar means that the two numbers divide themselves:
195/256,020 = 195 ÷ 256,020
Divide the numerator by the denominator to get the value of the fraction:
The value = 195 ÷ 256,020
Percentages, short introduction
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100
Note:
The fraction 100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value will not change.
To completely reduce (simplify) a fraction to its lowest terms, divide the numerator and the denominator of the fraction by their greatest (highest) common factor (divisor), gcf (hcf, gcd)
To calculate the greatest (highest) common factor (divisor), gcf (hcf, gcd), we perform the prime factorization of the two numbers.
The prime factorization of the two numbers:
The prime factorization of a number: finding the prime numbers that multiply together to make that number.
195 = 3 × 5 × 13
195 is not a prime number but a composite one.
256,020 = 22 × 3 × 5 × 17 × 251
256,020 is not a prime number but a composite one.
* The natural numbers that are only divisible by 1 and themselves are called prime numbers. A prime number has exactly two factors: 1 and itself.
* A composite number is a natural number that has at least one other factor than 1 and itself.
Calculate the greatest (highest) common factor (divisor), gcf (hcf, gcd):
Multiply all the common prime factors, taken by their smallest exponents (powers).
gcf, hcf, gcd (195; 256,020) = 3 × 5 = 15
Divide the numerator and the denominator of the fraction by their greatest (highest) common factor (divisor), gcf (hcf, gcd).
195/256,020 =
(3 × 5 × 13)/(22 × 3 × 5 × 17 × 251) =
((3 × 5 × 13) ÷ (3 × 5)) / ((22 × 3 × 5 × 17 × 251) ÷ (3 × 5)) =
13/(22 × 17 × 251) =
13/17,068
The fraction is now completely reduced (simplified) to its lowest terms.
A fraction that is completely reduced (simplified) to its lowest terms -- to its basic representation -- to its simplest form:
