# How do you solve (m-1)/8=2/4?

Dec 21, 2016

$m = 5$

#### Explanation:

Let's solve this equation step by step

Step 1: Cross-multiply.
$\frac{m - 1}{8} = \frac{2}{4}$
$4 m - 4 = 16$

Step 2: Add 4 to both sides.
4m−4+4=16+4
4m−4=16
$4 m = 20$

Step 3: Divide both sides by 4.
$\frac{4 m}{4} = \frac{20}{4}$
$m = 5$

Check solution
$\frac{5 - 1}{8} = \frac{2}{4}$
