Convert 1.527 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).

1.527 ≈ 1.52777777777778


Multiply the number by 100/100.

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

1.52777777777778 =

1.52777777777778 × 100/100 =

(1.52777777777778 × 100)/100 =

152.777777777778/100 =

152.777777777778% ≈

152.78%

(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, %
  • 1.527 ≈ 152.78%

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

  • 1.527 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 = 1.527


Set up the second equation.

  • Number of decimal places repeating: 1

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


y = 1.527

10 × y = 10 × 1.527

10 × y = 15.27

Get the same number of decimal places as for y:

10 × y = 15.277

Note: 15.277 = 15.27


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 = 15.277 - 1.527 ⇒

(10 - 1) × y = 15.277 - 1.527 ⇒

We now have a new equation:

9 × y = 13.75


Solve for y in the new equation.

9 × y = 13.75 ⇒

y = 13.75/9

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 1.527

According to our calculations:

y = 13.75/9

⇒ 1.527 = 13.75/9


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 100.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

1.527 = (13.75 × 100)/(9 × 100)

1.527 = 1,375/900


3. Reduce (simplify) the fraction above:
1,375/900
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).

1,375 = 53 × 11

900 = 22 × 32 × 52

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

Multiply all the common prime factors by the lowest exponents.

GCF (53 × 11; 22 × 32 × 52) = 52


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


Divide both the numerator and the denominator by their GCF.

1,375/900 =

(53 × 11)/(22 × 32 × 52) =

((53 × 11) ÷ 52) / ((22 × 32 × 52) ÷ 52) =

(5 × 11)/(22 × 32) =

55/36


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.

55 ÷ 36 = 1, remainder = 19 ⇒

55 = 1 × 36 + 19 ⇒

55/36 =

(1 × 36 + 19) / 36 =

(1 × 36) / 36 + 19/36 =

1 + 19/36 =

1 19/36


55/36 ~ 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 3.

55/36 = (55 × 3)/(36 × 3) = 165/108

Example 2. By expanding the fraction by 5.

55/36 = (55 × 5)/(36 × 5) = 275/180

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 55/36
