Use algebra, let x = 3.152 (repeating)
Then 1000x = 3152.152 (repeating)

Subtract the two:
1000x - x = 999x
3152.152 (repeating) - 3.152 (repeating) = 3149

So:
999x = 3149
x = 3149/999

Simplify the following: 2x3 - 2x2 - 4x / (over)

Marina86 [1]

$\frac{2x^3-2x^2-4x}{3x^3-12x}$

$\frac{2x.(x^2-x-2)}{3x.(x^2-4}$

$\frac{2}{3}.\frac{x^2-x-2}{x^2-4}$
