Question

Solve: $5z=8.5$

Answer 1

Step: Find the value of $z$

Given equation is $5z=8.5$

Dividing each term by $5$ we get,

$\Rightarrow \frac{5z}{5}=\frac{8.5}{5}$

$\Rightarrow z=\frac{8.5\times 10}{5\times 10}$

$\Rightarrow z=\frac{85}{50}=\frac{17}{10}$

[Dividing numerator and the denominator by $10$]

$\Rightarrow z=1.7$

Hence, the value of $z$ is $1.7$
