Convert 2.35 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).

2.35 ≈ 2.35353535353535


Multiply the number by 100/100.

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

2.35353535353535 =

2.35353535353535 × 100/100 =

(2.35353535353535 × 100)/100 =

235.353535353535/100 =

235.353535353535% ≈

235.35%

(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, %
  • 2.35 ≈ 235.35%

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

  • 2.35 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 = 2.35


Set up the second equation.

  • Number of decimal places repeating: 2

  • Multiply both sides of the first equation by 102 = 100


y = 2.35

100 × y = 100 × 2.35

100 × y = 235.35


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.

100 × y - y = 235.35 - 2.35 ⇒

(100 - 1) × y = 235.35 - 2.35 ⇒

We now have a new equation:

99 × y = 233


Solve for y in the new equation.

99 × y = 233 ⇒

y = 233/99

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 2.35

According to our calculations:

y = 233/99

⇒ 2.35 = 233/99


3. Reduce (simplify) the fraction above:
233/99
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).

233 is a prime number, it cannot be factored into other prime factors

99 = 32 × 11

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 (233; 32 × 11) = 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.

233 ÷ 99 = 2, remainder = 35 ⇒

233 = 2 × 99 + 35 ⇒

233/99 =

(2 × 99 + 35) / 99 =

(2 × 99) / 99 + 35/99 =

2 + 35/99 =

2 35/99


233/99 ~ 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.

233/99 = (233 × 2)/(99 × 2) = 466/198

Example 2. By expanding the fraction by 6.

233/99 = (233 × 6)/(99 × 6) = 1,398/594

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 233/99
