Convert 14.56 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).

14.56 ≈ 14.56666666666667


Multiply the number by 100/100.

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

14.56666666666667 =

14.56666666666667 × 100/100 =

(14.56666666666667 × 100)/100 =

1,456.666666666667/100 =

1,456.666666666667% ≈

1,456.67%

(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, %
  • 14.56 ≈ 1,456.67%

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

  • 14.56 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 = 14.56


Set up the second equation.

  • Number of decimal places repeating: 1

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


y = 14.56

10 × y = 10 × 14.56

10 × y = 145.6

Get the same number of decimal places as for y:

10 × y = 145.66

Note: 145.66 = 145.6


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 = 145.66 - 14.56 ⇒

(10 - 1) × y = 145.66 - 14.56 ⇒

We now have a new equation:

9 × y = 131.1


Solve for y in the new equation.

9 × y = 131.1 ⇒

y = 131.1/9

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 14.56

According to our calculations:

y = 131.1/9

⇒ 14.56 = 131.1/9


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.

14.56 = (131.1 × 10)/(9 × 10)

14.56 = 1,311/90


3. Reduce (simplify) the fraction above:
1,311/90
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).

1,311 = 3 × 19 × 23

90 = 2 × 32 × 5

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

Multiply all the common prime factors by the lowest exponents.

GCF (3 × 19 × 23; 2 × 32 × 5) = 3


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


Divide both the numerator and the denominator by their GCF.

1,311/90 =

(3 × 19 × 23)/(2 × 32 × 5) =

((3 × 19 × 23) ÷ 3) / ((2 × 32 × 5) ÷ 3) =

(19 × 23)/(2 × 3 × 5) =

437/30


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.

437 ÷ 30 = 14, remainder = 17 ⇒

437 = 14 × 30 + 17 ⇒

437/30 =

(14 × 30 + 17) / 30 =

(14 × 30) / 30 + 17/30 =

14 + 17/30 =

14 17/30


437/30 ~ 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.

437/30 = (437 × 4)/(30 × 4) = 1,748/120

Example 2. By expanding the fraction by 6.

437/30 = (437 × 6)/(30 × 6) = 2,622/180

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 437/30
