Convert 5.808 into equivalent fractions and write it as a percentage value

1. Write the number as a percentage.

  • Multiply the number by 100/100
  • Note: 100/100 = 1
  • The value of the number does not change when multiplying by 100/100

5.808 =


5.808 × 100/100 =


(5.808 × 100)/100 =


580.8/100 =


580.8%


  • In other words:
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 5.808 = 580.8%


2. Write the number as an improper fraction.

  • 5.808 can be written as an improper fraction.
  • An improper fraction = the numerator is larger than or equal to the denominator..

Write down the number divided by 1, as a fraction:

5.808 = 5.808/1


Turn the top number into a whole number.

  • Multiply both the top and the bottom by the same number.
  • This number is: 1,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

5.808/1 =


(5.808 × 1,000)/(1 × 1,000) =


5,808/1,000


3. Reduce (simplify) the fraction above:
5,808/1,000
to the lowest terms, to its simplest equivalent form, irreducible.

To reduce a fraction to the lowest terms divide the numerator and denominator by their greatest (highest) common factor (divisor), GCF.


Factor the numerator and denominator (prime factorization).

5,808 = 24 × 3 × 112


1,000 = 23 × 53



Calculate the greatest (highest) common factor (divisor), GCF.

Multiply all the common prime factors by the lowest exponents.


GCF (24 × 3 × 112; 23 × 53) = 23



Divide both the numerator and the denominator by their GCF.

5,808/1,000 =


(24 × 3 × 112)/(23 × 53) =


((24 × 3 × 112) ÷ 23) / ((23 × 53) ÷ 23) =


(2 × 3 × 112)/53 =


726/125


4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):

  • A mixed number = an integer number and a proper fraction, of the same sign.
  • Example 1: 2 1/5; Example 2: - 1 3/7.
  • A proper fraction = the numerator is smaller than the denominator.

726 ÷ 125 = 5, remainder = 101 ⇒


726 = 5 × 125 + 101 ⇒


726/125 =


(5 × 125 + 101) / 125 =


(5 × 125) / 125 + 101/125 =


5 + 101/125 =


5 101/125


726/125 ~ Equivalent fractions.

  • The above fraction cannot be reduced.
  • That is, it has the smallest possible numerator and denominator.
  • By expanding it we can build up equivalent fractions.

  • Multiply the numerator & the denominator by the same number.


Example 1. By expanding the fraction by 5.

726/125 = (726 × 5)/(125 × 5) = 3,630/625

Example 2. By expanding the fraction by 9.

726/125 = (726 × 9)/(125 × 9) = 6,534/1,125

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 726/125
