Convert 0.7275 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).

0.7275 ≈ 0.72757275727573


Multiply the number by 100/100.

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

0.72757275727573 =

0.72757275727573 × 100/100 =

(0.72757275727573 × 100)/100 =

72.757275727573/100 =

72.757275727573% ≈

72.76%

(rounded off to max. 2 decimal places)

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

  • 0.7275 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 = 0.7275


Set up the second equation.

  • Number of decimal places repeating: 4

  • Multiply both sides of the first equation by 104 = 10,000


y = 0.7275

10,000 × y = 10,000 × 0.7275

10,000 × y = 7,275.7275


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 = 7,275.7275 - 0.7275 ⇒

(10,000 - 1) × y = 7,275.7275 - 0.7275 ⇒

We now have a new equation:

9,999 × y = 7,275


Solve for y in the new equation.

9,999 × y = 7,275 ⇒

y = 7,275/9,999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.7275

According to our calculations:

y = 7,275/9,999

⇒ 0.7275 = 7,275/9,999


3. Reduce (simplify) the fraction above:
7,275/9,999
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).

7,275 = 3 × 52 × 97

9,999 = 32 × 11 × 101

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

Multiply all the common prime factors by the lowest exponents.

GCF (3 × 52 × 97; 32 × 11 × 101) = 3


» Calculate the greatest (highest) common factor (divisor), GCF, online calculator


Divide both the numerator and the denominator by their GCF.

7,275/9,999 =

(3 × 52 × 97)/(32 × 11 × 101) =

((3 × 52 × 97) ÷ 3) / ((32 × 11 × 101) ÷ 3) =

(52 × 97)/(3 × 11 × 101) =

2,425/3,333
