Answer:

case 1) z=10

case 2) z=5/32

Step-by-step explanation:

case 1) we know that

Using proportion

\frac{1}{z}=\frac{(4/5)}{8}

solve for z

\frac{1}{z}=\frac{(4/5)}{8}\\ \\z(4/5)=8\\ \\z=8*5/4\\ \\z=10

case 2) we know that

Using proportion

\frac{1}{z}=\frac{4}{5/8}

solve for z

\frac{1}{z}=\frac{4}{5/8}\\ \\4z=5/8\\ \\z=5/32
