Convert 4.73 into equivalent fractions and write it as a percentage value

1. Write the mixed repeating (recurring) decimal number as a percentage.

Approximate to the desired number of decimal places (14).

4.73 ≈ 4.73333333333333


Multiply the number by 100/100.

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

4.73333333333333 =

4.73333333333333 × 100/100 =

(4.73333333333333 × 100)/100 =

473.333333333333/100 =

473.333333333333% ≈

473.33%

(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, %
  • 4.73 ≈ 473.33%

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

  • 4.73 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 = 4.73


Set up the second equation.

  • Number of decimal places repeating: 1

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


y = 4.73

10 × y = 10 × 4.73

10 × y = 47.3

Get the same number of decimal places as for y:

10 × y = 47.33

Note: 47.33 = 47.3


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 = 47.33 - 4.73 ⇒

(10 - 1) × y = 47.33 - 4.73 ⇒

We now have a new equation:

9 × y = 42.6


Solve for y in the new equation.

9 × y = 42.6 ⇒

y = 42.6/9

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 4.73

According to our calculations:

y = 42.6/9

⇒ 4.73 = 42.6/9


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

4.73 = (42.6 × 10)/(9 × 10)

4.73 = 426/90


3. Reduce (simplify) the fraction above:
426/90
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).

426 = 2 × 3 × 71

90 = 2 × 32 × 5

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

Multiply all the common prime factors by the lowest exponents.

GCF (2 × 3 × 71; 2 × 32 × 5) = 2 × 3


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


Divide both the numerator and the denominator by their GCF.

426/90 =

(2 × 3 × 71)/(2 × 32 × 5) =

((2 × 3 × 71) ÷ (2 × 3)) / ((2 × 32 × 5) ÷ (2 × 3)) =

71/(3 × 5) =

71/15


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.

71 ÷ 15 = 4, remainder = 11 ⇒

71 = 4 × 15 + 11 ⇒

71/15 =

(4 × 15 + 11) / 15 =

(4 × 15) / 15 + 11/15 =

4 + 11/15 =

4 11/15


71/15 ~ 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.

71/15 = (71 × 2)/(15 × 2) = 142/30

Example 2. By expanding the fraction by 5.

71/15 = (71 × 5)/(15 × 5) = 355/75

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 71/15
