Convert 0.008 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).
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
0.00808080808081 =
0.00808080808081 × 100/100 =
(0.00808080808081 × 100)/100 =
0.808080808081/100 =
0.808080808081% ≈
0.81%
(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, %
- 0.008 ≈ 0.81%
2. Write the mixed repeating (recurring) decimal number as a proper fraction.
0.008 can be written as a proper fraction.
- The numerator is smaller than the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 0.008
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 0.008
100 × y = 100 × 0.008
100 × y = 0.808
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 = 0.808 - 0.008 ⇒
(100 - 1) × y = 0.808 - 0.008 ⇒
We now have a new equation:
99 × y = 0.8
Solve for y in the new equation.
99 × y = 0.8 ⇒
y = 0.8/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.008
According to our calculations:
y = 0.8/99
⇒ 0.008 = 0.8/99
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.
0.008 = (0.8 × 10)/(99 × 10)
0.008 = 8/990
3. Reduce (simplify) the fraction above:
8/990
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).
8 = 23
990 = 2 × 32 × 5 × 11
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23; 2 × 32 × 5 × 11) = 2
Divide both the numerator and the denominator by their GCF.
8/990 =
23/(2 × 32 × 5 × 11) =
(23 ÷ 2) / ((2 × 32 × 5 × 11) ÷ 2) =
22/(32 × 5 × 11) =
4/495
4/495 ~ 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.
4/495 = (4 × 5)/(495 × 5) = 20/2,475
Example 2. By expanding the fraction by 6.
4/495 = (4 × 6)/(495 × 6) = 24/2,970
- Of course, the above fractions are reducing...
- ... to the initial fraction: 4/495
:: Final answer ::
Written in 3 different ways
As a reduced (simplified) positive proper fraction:
0.008 = 4/495
As a percentage:
0.008 ≈ 0.81%
As equivalent fractions:
0.008 = 4/495 = 20/2,475 = 24/2,970
