Question

Solve for z in the problem below:

4/5 = z/20

A.z = 16

B. z = 80

C. z = 13

D. z = 5

​

Answer 1

Answer:

A

Step-by-step explanation:

Given

$\frac{4}{5}$ = $\frac{z}{20}$

Multiply both sides by 20 to clear the fractions

16 = z → A

Answer 2

Answer:

A. z = 16

Step-by-step explanation:

Multiply both sides by 20 isolate the variable z.

$\frac{4}{5} *\frac{z}{20}$

$\frac{4}{5} *20 = \frac{z}{20} *20$

$z = \frac{4}{5} *20$

Multiplying $\frac{4}{5}$ by 20 will give us 16.

$\frac{4}{5} *\frac{20}{1} = \frac{80}{5}$$= 16$

Therefore, z is equal to 16.
