Question

$$\frac{z}{7}=\frac{1}{21}$$

Solve for z

$z=\frac{1}{3}\approx 0.333333333$

Steps for Solving Linear Equation

Multiply both sides by $7$.

$$z=\frac{1}{21}\times 7$$

Multiply $\frac{1}{21}$ and $7$ to get $\frac{7}{21}$.

$$z=\frac{7}{21}$$

Reduce the fraction $\frac{7}{21}$ to lowest terms by extracting and canceling out $7$.

$$z=\frac{1}{3}$$
