Convert 5.08 into equivalent fractions and write it as a percentage value

1. Write the pure repeating (recurring) decimal number as a percentage.

Approximate to the desired number of decimal places (14).

5.085.08080808080808


Multiply the number by 100/100.

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

5.08080808080808 =


5.08080808080808 × 100/100 =


(5.08080808080808 × 100)/100 =


508.080808080808/100 =


508.080808080808% ≈


508.08%


(rounded off to max. 2 decimal places)


  • In other words:
  • Approximate to the desired number of decimal places...
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 5.08508.08%


2. Write the pure repeating (recurring) decimal number as an improper fraction.

  • 5.08 can be written as an improper fraction.

  • The numerator is larger than or equal to the denominator.

Set up the first equation.

  • Let y equal the decimal number:
  • y = 5.08


Set up the second equation.

  • Number of decimal places repeating: 2
  • Multiply both sides of the first equation by 102 = 100


y = 5.08


100 × y = 100 × 5.08


100 × y = 508.08


Subtract the first equation from the second one.

  • Having the same number of decimal places ...
  • The repeating pattern drops off by subtracting the two equations.

100 × y - y = 508.08 - 5.08


(100 - 1) × y = 508.08 - 5.08


We now have a new equation:


99 × y = 503


Solve for y in the new equation.

99 × y = 503 ⇒


y = 503/99


Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 5.08


According to our calculations:

y = 503/99


⇒ 5.08 = 503/99


3. Reduce (simplify) the fraction above:
503/99
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).

503 is a prime number, it cannot be factored into other prime factors


99 = 32 × 11



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

Multiply all the common prime factors by the lowest exponents.

But, the numerator and the denominator have no common factors.


GCF (503; 32 × 11) = 1




The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.


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.

503 ÷ 99 = 5, remainder = 8 ⇒


503 = 5 × 99 + 8 ⇒


503/99 =


(5 × 99 + 8) / 99 =


(5 × 99) / 99 + 8/99 =


5 + 8/99 =


5 8/99


503/99 ~ 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.

503/99 = (503 × 5)/(99 × 5) = 2,515/495

Example 2. By expanding the fraction by 7.

503/99 = (503 × 7)/(99 × 7) = 3,521/693

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 503/99


:: Final answer ::
Written in 4 different ways

As a reduced (simplified) positive improper fraction:
5.08 = 503/99
