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 :

41

Simplify ———

:

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

Equation at the end of step

:

1000n - 41

—————————— = 0

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
