Convert 34.6 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).

34.6 ≈ 34.66666666666667


Multiply the number by 100/100.

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

34.66666666666667 =

34.66666666666667 × 100/100 =

(34.66666666666667 × 100)/100 =

3,466.666666666667/100 =

3,466.666666666667% ≈

3,466.67%

(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, %
  • 34.6 ≈ 3,466.67%

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

  • 34.6 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 = 34.6


Set up the second equation.

  • Number of decimal places repeating: 1

  • Multiply both sides of the first equation by 101 = 10


y = 34.6

10 × y = 10 × 34.6

10 × y = 346.6


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 = 346.6 - 34.6 ⇒

(10 - 1) × y = 346.6 - 34.6 ⇒

We now have a new equation:

9 × y = 312


Solve for y in the new equation.

9 × y = 312 ⇒

y = 312/9

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 34.6

According to our calculations:

y = 312/9

⇒ 34.6 = 312/9


3. Reduce (simplify) the fraction above:
312/9
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).

312 = 23 × 3 × 13

9 = 32

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

Multiply all the common prime factors by the lowest exponents.

GCF (23 × 3 × 13; 32) = 3


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


Divide both the numerator and the denominator by their GCF.

312/9 =

(23 × 3 × 13)/32 =

((23 × 3 × 13) ÷ 3) / (32 ÷ 3) =

(23 × 13)/3 =

104/3


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.

104 ÷ 3 = 34, remainder = 2 ⇒

104 = 34 × 3 + 2 ⇒

104/3 =

(34 × 3 + 2) / 3 =

(34 × 3) / 3 + 2/3 =

34 + 2/3 =

34 2/3


104/3 ~ 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.

104/3 = (104 × 4)/(3 × 4) = 416/12

Example 2. By expanding the fraction by 7.

104/3 = (104 × 7)/(3 × 7) = 728/21

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 104/3
