Answer:
[tex]z= \frac{1}{3}[/tex]
Explanation:
Given
[tex]\frac{z}{7} = \frac{1}{21}[/tex]
Required
Solve
[tex]\frac{z}{7} = \frac{1}{21}[/tex]
Multiply both sides by 7
[tex]7 * \frac{z}{7} = \frac{1}{21} * 7[/tex]
[tex]z= \frac{1}{21} * 7[/tex]
Rewrite as:
[tex]z= \frac{1 * 7}{21}[/tex]
[tex]z= \frac{7}{21}[/tex]
Simplify fraction
[tex]z= \frac{1}{3}[/tex]
