im not sure

Answer 22

\[\frac{ 30 }{ 100 }\rightarrow biography\]
\[\frac{ 50 }{ 100 }\rightarrow mystery\]
\[\frac{ 20 }{ 100 }\rightarrow science\]
multiply all that together..
\[\frac{ 30 }{ 100 }\times \frac{ 50 }{ 100 }\times \frac{ 20 }{ 100 }=\frac{ 30 }{ 100 }\]
and if you had to change\[\frac{ 30 }{ 100 }\]it would be \[0.3\]
