Convert 0.16666668 into equivalent fractions and write it as a percentage value

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

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

0.166666680.16666668666867


Multiply the number by 100/100.

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

0.16666668666867 =


0.16666668666867 × 100/100 =


(0.16666668666867 × 100)/100 =


16.666668666867/100 =


16.666668666867% ≈

(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, %
  • 0.1666666816.67%


2. Write the mixed repeating (recurring) decimal number as a proper fraction.

  • 0.16666668 can be written as a proper fraction.

  • The numerator is smaller than the denominator.

Set up the first equation.

  • Let y equal the decimal number:
  • y = 0.16666668


Set up the second equation.

  • Number of decimal places repeating: 4
  • Multiply both sides of the first equation by 104 = 10,000


y = 0.16666668


10,000 × y = 10,000 × 0.16666668


10,000 × y = 1,666.6668


Get the same number of decimal places as for y:


10,000 × y = 1,666.66686668


Note: 1,666.66686668 = 1,666.6668


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.

10,000 × y - y = 1,666.66686668 - 0.16666668


(10,000 - 1) × y = 1,666.66686668 - 0.16666668


We now have a new equation:


9,999 × y = 1,666.5002


Solve for y in the new equation.

9,999 × y = 1,666.5002 ⇒


y = 1,666.5002/9,999


Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.16666668


According to our calculations:

y = 1,666.5002/9,999


⇒ 0.16666668 = 1,666.5002/9,999


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

0.16666668 = (1,666.5002 × 10,000)/(9,999 × 10,000)


0.16666668 = 16,665,002/99,990,000


3. Reduce (simplify) the fraction above:
16,665,002/99,990,000
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).

16,665,002 = 2 × 53 × 157,217


99,990,000 = 24 × 32 × 54 × 11 × 101



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

Multiply all the common prime factors by the lowest exponents.


GCF (2 × 53 × 157,217; 24 × 32 × 54 × 11 × 101) = 2



Divide both the numerator and the denominator by their GCF.

16,665,002/99,990,000 =


(2 × 53 × 157,217)/(24 × 32 × 54 × 11 × 101) =


((2 × 53 × 157,217) ÷ 2) / ((24 × 32 × 54 × 11 × 101) ÷ 2) =


(53 × 157,217)/(23 × 32 × 54 × 11 × 101) =
