Question

Z 1
-- = --
7 21
solve​

Answer 1

`z= (1)/(3)`

Step-by-step explanation:

Given

`(z)/(7) = (1)/(21)`

Required

Solve

`(z)/(7) = (1)/(21)`

Multiply both sides by 7

`7 * (z)/(7) = (1)/(21) * 7`

`z= (1)/(21) * 7`

Rewrite as:

`z= (1 * 7)/(21)`

`z= (7)/(21)`

Simplify fraction

`z= (1)/(3)`
