Convert 1.0001 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

1.0001 =


1.0001 × 100/100 =


(1.0001 × 100)/100 =


100.01/100 =


100.01%


  • In other words:
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 1.0001 = 100.01%


2. Write the number as an improper fraction.

  • 1.0001 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:

1.0001 = 1.0001/1


Turn the top number into a whole number.

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

1.0001/1 =


(1.0001 × 10,000)/(1 × 10,000) =


10,001/10,000


3. Reduce (simplify) the fraction above:
10,001/10,000
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).

10,001 = 73 × 137


10,000 = 24 × 54



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 (73 × 137; 24 × 54) = 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.

10,001 ÷ 10,000 = 1, remainder = 1 ⇒


10,001 = 1 × 10,000 + 1 ⇒


10,001/10,000 =


(1 × 10,000 + 1) / 10,000 =


(1 × 10,000) / 10,000 + 1/10,000 =


1 + 1/10,000 =


1 1/10,000


10,001/10,000 ~ 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 4.

10,001/10,000 = (10,001 × 4)/(10,000 × 4) = 40,004/40,000

Example 2. By expanding the fraction by 7.

10,001/10,000 = (10,001 × 7)/(10,000 × 7) = 70,007/70,000

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 10,001/10,000


:: Final answer ::
Written in 4 different ways

As a reduced (simplified) positive improper fraction:
1.0001 = 10,001/10,000

As a mixed number:
1.0001 = 1 1/10,000

As a percentage:
1.0001 = 100.01%

As equivalent fractions:
1.0001 = 10,001/10,000 = 40,004/40,000 = 70,007/70,000
