Answer 1

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]
