Convert 0.00005 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).
0.00005 ≈ 0.00005555555556
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
0.00005555555556 =
0.00005555555556 × 100/100 =
(0.00005555555556 × 100)/100 =
0.005555555556/100 =
0.005555555556% ≈
0.01%
(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, %
- 0.00005 ≈ 0.01%
2. Write the mixed repeating (recurring) decimal number as a proper fraction.
0.00005 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 = 0.00005
Set up the second equation.
- Number of decimal places repeating: 1
Multiply both sides of the first equation by 101 = 10
y = 0.00005
10 × y = 10 × 0.00005
10 × y = 0.0005
Get the same number of decimal places as for y:
10 × y = 0.00055
Note: 0.00055 = 0.0005
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 = 0.00055 - 0.00005 ⇒
(10 - 1) × y = 0.00055 - 0.00005 ⇒
We now have a new equation:
9 × y = 0.0005
Solve for y in the new equation.
9 × y = 0.0005 ⇒
y = 0.0005/9
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.00005
According to our calculations:
y = 0.0005/9
⇒ 0.00005 = 0.0005/9
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 10,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.00005 = (0.0005 × 10,000)/(9 × 10,000)
0.00005 = 5/90,000
3. Reduce (simplify) the fraction above:
5/90,000
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 is a prime number, it cannot be factored into other prime factors
90,000 = 24 × 32 × 54
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (5; 24 × 32 × 54) = 5
Divide both the numerator and the denominator by their GCF.
5/90,000 =
5/(24 × 32 × 54) =
(5 ÷ 5) / ((24 × 32 × 54) ÷ 5) =
1/(24 × 32 × 53) =
1/18,000
1/18,000 ~ 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 6.
1/18,000 = (1 × 6)/(18,000 × 6) = 6/108,000
Example 2. By expanding the fraction by 8.
1/18,000 = (1 × 8)/(18,000 × 8) = 8/144,000
- Of course, the above fractions are reducing...
- ... to the initial fraction: 1/18,000
:: Final answer ::
Written in 3 different ways
As a reduced (simplified) positive proper fraction:
0.00005 = 1/18,000
As a percentage:
0.00005 ≈ 0.01%
As equivalent fractions:
0.00005 = 1/18,000 = 6/108,000 = 8/144,000
