What is \[0.9\%\] as a decimal?

Hint: In this problem, we have to find the decimal part from the given percentage. We should know that the given percentage can be converted into its fraction part as we know that dividing a number by 100 is a percent of the number. we can then multiply both numerator and the denominator with 10, we can then divide the resulting fraction by moving the decimal points to the left as we divide to get the decimal value.

Complete step-by-step answer:
Here we have to find the decimal value of the given percentage \[0.9\%\].
We can now write the given percentage as,
\[= \dfrac{0.9}{100}\]
We can now multiply 10 on both the numerator and the denominator, we get
\[= \dfrac{0.9}{100}\times \dfrac{10}{10}=\dfrac{9}{1000}\]
We can now divide the above fraction, we will get the decimal number, where decimal point moves three points to the left, we get
\[= 0.009\]
Therefore, the decimal value of the given percentage \[0.9\%\] is 0.009.

Note: We should also know that, percent means 100. We should know that to convert a percentage into a decimal, we can divide the given number by hundred and we can drop the percentage symbol, where we can move the decimal three points to the left as we divide the decimal point.
\[= \dfrac{0.9}{100}\]
Here we can move the decimal three points to the left, we get
\[= 0.009\]
Therefore, the decimal value of the given percentage \[0.9\%\] is 0.009.
