Convert 1.001 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).

1.0011.00111111111111


Multiply the number by 100/100.

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

1.00111111111111 =


1.00111111111111 × 100/100 =


(1.00111111111111 × 100)/100 =


100.111111111111/100 =


100.111111111111% ≈


100.11%


(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, %
  • 1.001100.11%


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

  • 1.001 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 = 1.001


Set up the second equation.

  • Number of decimal places repeating: 1
  • Multiply both sides of the first equation by 101 = 10


y = 1.001


10 × y = 10 × 1.001


10 × y = 10.01


Get the same number of decimal places as for y:


10 × y = 10.011


Note: 10.011 = 10.01


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 × y - y = 10.011 - 1.001


(10 - 1) × y = 10.011 - 1.001


We now have a new equation:


9 × y = 9.01


Solve for y in the new equation.

9 × y = 9.01 ⇒


y = 9.01/9


Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 1.001


According to our calculations:

y = 9.01/9


⇒ 1.001 = 9.01/9


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 100.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

1.001 = (9.01 × 100)/(9 × 100)


1.001 = 901/900


3. Reduce (simplify) the fraction above:
901/900
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).

901 = 17 × 53


900 = 22 × 32 × 52



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 (17 × 53; 22 × 32 × 52) = 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.

901 ÷ 900 = 1, remainder = 1 ⇒


901 = 1 × 900 + 1 ⇒


901/900 =


(1 × 900 + 1) / 900 =


(1 × 900) / 900 + 1/900 =


1 + 1/900 =


1 1/900


901/900 ~ 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.

901/900 = (901 × 5)/(900 × 5) = 4,505/4,500

Example 2. By expanding the fraction by 6.

901/900 = (901 × 6)/(900 × 6) = 5,406/5,400

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 901/900


:: Final answer ::
Written in 4 different ways

As a reduced (simplified) positive improper fraction:
1.001 = 901/900

As a mixed number:
1.001 = 1 1/900

As a percentage:
1.001 ≈ 100.11%

As equivalent fractions:
1.001 = 901/900 = 4,505/4,500 = 5,406/5,400
