we know that
[tex] \frac{1}{10}= 10\%[/tex]
[tex] \frac{1}{10} [/tex] of [tex] 0.09 [/tex] is equal to find the [tex] 10\% [/tex] of the number [tex] 0.09 [/tex]
so
Multiply [tex] \frac{1}{10} [/tex] by the number [tex] 0.09 [/tex]
[tex] \frac{1}{10} * 0.09= \frac{1}{10} * \frac{9}{100}=\frac{9}{1000}= 0.009[/tex]
therefore
the answer is
[tex] 0.009 [/tex]
