Convert 0.001266 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.

0.0012660.001266001266


Multiply the number by 100/100.

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

0.001266001266 =


0.001266001266 × 100/100 =


(0.001266001266 × 100)/100 =


0.1266001266/100 =


0.1266001266% ≈


0.13%


(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, %
  • 0.0012660.13%


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

  • 0.001266 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 = 0.001266


Set up the second equation.

  • Number of decimal places repeating: 6
  • Multiply both sides of the first equation by 106 = 1,000,000


y = 0.001266


1,000,000 × y = 1,000,000 × 0.001266


1,000,000 × y = 1,266.001266


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.

1,000,000 × y - y = 1,266.001266 - 0.001266


(1,000,000 - 1) × y = 1,266.001266 - 0.001266


We now have a new equation:


999,999 × y = 1,266


Solve for y in the new equation.

999,999 × y = 1,266 ⇒


y = 1,266/999,999


Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.001266


According to our calculations:

y = 1,266/999,999


⇒ 0.001266 = 1,266/999,999


3. Reduce (simplify) the fraction above:
1,266/999,999
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).

1,266 = 2 × 3 × 211


999,999 = 33 × 7 × 11 × 13 × 37



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

Multiply all the common prime factors by the lowest exponents.


GCF (2 × 3 × 211; 33 × 7 × 11 × 13 × 37) = 3



Divide both the numerator and the denominator by their GCF.

1,266/999,999 =


(2 × 3 × 211)/(33 × 7 × 11 × 13 × 37) =


((2 × 3 × 211) ÷ 3) / ((33 × 7 × 11 × 13 × 37) ÷ 3) =


(2 × 211)/(32 × 7 × 11 × 13 × 37) =


422/333,333
