Question

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

Answer 1

case 1)
`z=10`

case 2)
`z=5/32`

Explanation:

case 1) we know that

Using proportion

`(1)/(z)=((4/5))/(8)`

solve for z

`(1)/(z)=((4/5))/(8)\\ \\z(4/5)=8\\ \\z=8*5/4\\ \\z=10`

case 2) we know that

Using proportion

`(1)/(z)=(4)/(5/8)`

solve for z

`(1)/(z)=(4)/(5/8)\\ \\4z=5/8\\ \\z=5/32`
