Answer Reformatting the input :
Changes made to your input should not affect the solution:
(1): "0.328" was replaced by "(328/1000)".
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
8*n-((328/1000))=0
Step by step solution :

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 125 as the denominator :
8n 8n • 125
8n = —— = ————————
1 125
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
8n • 125 - (41) 1000n - 41
——————————————— = ——————————
125 125

When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
1000n-41
———————— • 125 = 0 • 125
125
Now, on the left hand side, the 125 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
1000n-41 = 0
Solving a Single Variable Equation:
3.2 Solve : 1000n-41 = 0
Add 41 to both sides of the equation :
1000n = 41
Divide both sides of the equation by 1000:
n = 41/1000 = 0.041
