Question

8 = x divided by 12.8

Answer 1

       8 = x / 12.8
102.4 = x

Therefore x = 102.4

Answer 2

8 = x divided by 12.8 means this:
8 = $\frac{x}{12.8}$

To solve for x, we need to get rid of the denominator, 12.8.
To do that, we need to cancel it out by multiplying by 12.8.

Multiply both sides by 12.8.

8 * 12.8 = 102.4.
$\frac{x}{12.8}$ * 12.8 = x

We are now left with:
x = 102.4
