Convert 5.87 into equivalent fractions and write it as a percentage value
1. Write the pure repeating (recurring) decimal number as a percentage.
Approximate to the desired number of decimal places (14).
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
5.87878787878788 =
5.87878787878788 × 100/100 =
(5.87878787878788 × 100)/100 =
587.878787878788/100 =
587.878787878788% ≈
587.88%
(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, %
- 5.87 ≈ 587.88%
2. Write the pure repeating (recurring) decimal number as an improper fraction.
5.87 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 = 5.87
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 5.87
100 × y = 100 × 5.87
100 × y = 587.87
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.
100 × y - y = 587.87 - 5.87 ⇒
(100 - 1) × y = 587.87 - 5.87 ⇒
We now have a new equation:
99 × y = 582
Solve for y in the new equation.
99 × y = 582 ⇒
y = 582/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 5.87
According to our calculations:
y = 582/99
⇒ 5.87 = 582/99
3. Reduce (simplify) the fraction above:
582/99
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).
582 = 2 × 3 × 97
99 = 32 × 11
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 3 × 97; 32 × 11) = 3
Divide both the numerator and the denominator by their GCF.
582/99 =
(2 × 3 × 97)/(32 × 11) =
((2 × 3 × 97) ÷ 3) / ((32 × 11) ÷ 3) =
(2 × 97)/(3 × 11) =
194/33
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.
194 ÷ 33 = 5, remainder = 29 ⇒
194 = 5 × 33 + 29 ⇒
194/33 =
(5 × 33 + 29) / 33 =
(5 × 33) / 33 + 29/33 =
5 + 29/33 =
5 29/33
194/33 ~ 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.
194/33 = (194 × 4)/(33 × 4) = 776/132
Example 2. By expanding the fraction by 7.
194/33 = (194 × 7)/(33 × 7) = 1,358/231
- Of course, the above fractions are reducing...
- ... to the initial fraction: 194/33
:: Final answer ::
