Convert 0.5457 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

0.5457 =

0.5457 × 100/100 =

(0.5457 × 100)/100 =

54.57/100 =

54.57%


  • In other words:
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 0.5457 = 54.57%

2. Write the number as a proper fraction.

  • 0.5457 can be written as a proper fraction.
  • A proper fraction = the numerator is smaller than the denominator..

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

0.5457 = 0.5457/1


Turn the top number into a whole number.

  • Multiply both the top and the bottom by the same number.
  • This number is: 10,000.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

0.5457/1 =

(0.5457 × 10,000)/(1 × 10,000) =

5,457/10,000


3. Reduce (simplify) the fraction above:
5,457/10,000
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).

5,457 = 3 × 17 × 107

10,000 = 24 × 54

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

Multiply all the common prime factors by the lowest exponents.

But, the numerator and the denominator have no common factors.

GCF (3 × 17 × 107; 24 × 54) = 1


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


The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.


5,457/10,000 ~ 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 5.

5,457/10,000 = (5,457 × 5)/(10,000 × 5) = 27,285/50,000

Example 2. By expanding the fraction by 7.

5,457/10,000 = (5,457 × 7)/(10,000 × 7) = 38,199/70,000

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 5,457/10,000
