SOLUTION
We want to solve
[tex]\frac{1}{2}\text{ of 1\% of 190}[/tex]Of is the same as multiplication. So we have
[tex]\begin{gathered} \frac{1}{2}\text{ of 1\% of 190} \\ \frac{1}{2}\times1\%\times190 \\ 1\%\text{ means }\frac{1}{100},\text{ so we have } \\ \frac{1}{2}\times\frac{1}{100}\times190 \\ one\text{ zeros in 100 and 190 cancels, we have } \\ \frac{1}{2}\times\frac{1}{10}\times19 \end{gathered}[/tex]This becomes
[tex]\begin{gathered} \frac{1\times1\times19}{2\times10} \\ =\frac{19}{20} \end{gathered}[/tex]Hence the answer is
[tex]\frac{19}{20}[/tex]
