Convert the decimal number 8.54. Turn it into a reduced (simplified) improper fraction, into a mixed number and write it as a percentage value. Equivalent fractions calculator

Convert 8.54 into equivalent fractions and write it as a percentage value

1. Write the number as a percentage.

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

8.54 =

8.54 × 100/100 =

(8.54 × 100)/100 =

854/100 =

854%


  • In other words:
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 8.54 = 854%

2. Write the number as an improper fraction.

  • 8.54 can be written as an improper fraction.
  • An improper fraction = the numerator is larger than or equal to the denominator..

Write down the number divided by 1, as a fraction:

8.54 = 8.54/1


Turn the top number into a whole number.

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

8.54/1 =

(8.54 × 100)/(1 × 100) =

854/100


3. Reduce (simplify) the fraction above:
854/100
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).

854 = 2 × 7 × 61

100 = 22 × 52

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

Multiply all the common prime factors by the lowest exponents.

GCF (2 × 7 × 61; 22 × 52) = 2


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


Divide both the numerator and the denominator by their GCF.

854/100 =

(2 × 7 × 61)/(22 × 52) =

((2 × 7 × 61) ÷ 2) / ((22 × 52) ÷ 2) =

(7 × 61)/(2 × 52) =

427/50


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.

427 ÷ 50 = 8, remainder = 27 ⇒

427 = 8 × 50 + 27 ⇒

427/50 =

(8 × 50 + 27) / 50 =

(8 × 50) / 50 + 27/50 =

8 + 27/50 =

8 27/50


427/50 ~ 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.

427/50 = (427 × 3)/(50 × 3) = 1,281/150

Example 2. By expanding the fraction by 4.

427/50 = (427 × 4)/(50 × 4) = 1,708/200

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 427/50
