\frac{170}{85}=\frac{z}{0.01}
Expand \frac{17}{8.5} by multiplying both numerator and the denominator by 10.
2=\frac{z}{0.01}
Divide 170 by 85 to get 2.
\frac{z}{0.01}=2
Swap sides so that all variable terms are on the left hand side.
z=2\times 0.01
Multiply both sides by 0.01.
z=0.02
Multiply 2 and 0.01 to get 0.02.
