Question

In the poportion 1/z =4/5/8 which number is equal to z in the proportion

Answer 1

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

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