Reduce (simplify) the fraction: 340/9
Detailed calculations below:
Fractions, brief introduction
A fraction consists of two numbers and the fraction bar: 340/9
The number above the fraction bar is the numerator: 340
The number under the fraction bar is the denominator: 9
The fraction bar means that the two numbers divide themselves:
340/9 = 340 ÷ 9
Divide the numerator by the denominator to get the value of the fraction:
The value = 340 ÷ 9
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.
340 = 22 × 5 × 17
340 is not a prime number but a composite one.
9 = 32
9 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).
But the two numbers have no common prime factors:
gcf, hcf, gcd (340; 9) = 1
Coprime numbers (prime to each other, relatively prime)
The fraction cannot be reduced (simplified)
The numerator and denominator of the fraction are relatively prime numbers (coprime, prime to each other).
The only common factor (divisor) of the two numbers is 1.
340/9 is an improper fraction.
An improper fraction: the numerator is greater than or equal to the denominator.
Rewrite the fraction:
As a mixed number (mixed fraction):
A mixed number: an integer and a proper fraction that have the same sign.
The original improper fraction is obtained by adding the integer number and the proper fraction.
A proper fraction: the numerator is smaller than the denominator.
340 ÷ 9 = 37 and Remainder = 7 =>
340 = 37 × 9 + 7 =>
340/9 =
(37 × 9 + 7) / 9 =
(37 × 9) / 9 + 7 / 9 =
37 + 7/9 =
37 7/9
As a decimal number:
37 7/9 =
37 + 7/9 =
37 + 7 ÷ 9 ≈
37.777777777778 ≈
37.78
As a percentage:
37.777777777778 =
37.777777777778 × 100/100 =
3,777.777777777778/100 =
3,777.777777777778% ≈
3,777.78%
In other words:
1) Calculate the value of the fraction.
2) Multiply this number by 100.
3) Add the percent sign, %.
