Convert 0.259 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).

0.259 ≈ 0.25925925925926


Multiply the number by 100/100.

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

0.25925925925926 =

0.25925925925926 × 100/100 =

(0.25925925925926 × 100)/100 =

25.925925925926/100 =

25.925925925926% ≈

25.93%

(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, %
  • 0.259 ≈ 25.93%

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

  • 0.259 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 = 0.259


Set up the second equation.

  • Number of decimal places repeating: 3

  • Multiply both sides of the first equation by 103 = 1,000


y = 0.259

1,000 × y = 1,000 × 0.259

1,000 × y = 259.259


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 × y - y = 259.259 - 0.259 ⇒

(1,000 - 1) × y = 259.259 - 0.259 ⇒

We now have a new equation:

999 × y = 259


Solve for y in the new equation.

999 × y = 259 ⇒

y = 259/999

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 0.259

According to our calculations:

y = 259/999

⇒ 0.259 = 259/999


3. Reduce (simplify) the fraction above:
259/999
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).

259 = 7 × 37

999 = 33 × 37

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

Multiply all the common prime factors by the lowest exponents.

GCF (7 × 37; 33 × 37) = 37


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


Divide both the numerator and the denominator by their GCF.

259/999 =

(7 × 37)/(33 × 37) =

((7 × 37) ÷ 37) / ((33 × 37) ÷ 37) =

7/33 =

7/27


7/27 ~ 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 2.

7/27 = (7 × 2)/(27 × 2) = 14/54

Example 2. By expanding the fraction by 5.

7/27 = (7 × 5)/(27 × 5) = 35/135

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 7/27

Learn how to turn a decimal number into a fraction and a percentage. Steps.

1. How to write the number as a percentage:

  • Multiply the number by 100. Then add the percent sign, %.

2. How to write the number as a fraction:

  • Write down the number divided by 1, as a fraction.
  • Turn the top number into a whole number: multiply both the top and the bottom by the same number.
  • Reduce (simplify) the above fraction to the lowest terms, to its simplest equivalent form, irreducible. To reduce a fraction divide the numerator and the denominator by their greatest (highest) common factor (divisor), GCF.
  • If the fraction is an improper one, rewrite it as a mixed number (mixed fraction).
  • Calculate equivalent fractions. By expanding it we can build up equivalent fractions: multiply the numerator & the denominator by the same number.
