Answer 2

I think is:
\[\frac{ 3 }{ \frac{ 1 }{ 9 } }=\frac{ 3 }{ 1 }\times \frac{ 9 }{ 1 }=27\]

Answer 3

so um what do those brackets and slashes mean? i'm gonna guess 27 do to the equal sign

Answer 4

because you have to multiply the first fraction by the inverse of the second fraction, in order to divide two fractions. The fraction you have to divide each other are:
3/1 and 1/9.
