Answer:

A

Explanation:

Given


(4)/(5) =
(z)/(20)

Multiply both sides by 20 to clear the fractions

Answer:

A. z = 16

Explanation:

Multiply both sides by 20 isolate the variable z.


(4)/(5) *(z)/(20)


(4)/(5) *20 = (z)/(20) *20


z = (4)/(5) *20

Multiplying
(4)/(5) by 20 will give us 16.


(4)/(5) *(20)/(1) = (80)/(5)
= 16

Therefore, z is equal to 16.
