# How do you evaluate (4ab)/(8c), where a=8, b=4, and c=1/2?

$32$

#### Explanation:

To solve this expression, we plug in the numbers it has given us in the problem, and then simply solve.

So because of the information given, we rewrite the expression as:

$\frac{4 a b}{8 c} \implies \frac{4 \left(8\right) \left(4\right)}{8 \left(\frac{1}{2}\right)}$

Now we can solve the expression:

$\frac{4 \left(8\right) \left(4\right)}{8 \left(\frac{1}{2}\right)} \implies \frac{\left(32\right) \left(4\right)}{4} \implies \frac{128}{4} \implies 32$

$\frac{4 \left(8\right) \left(4\right)}{8 \left(\frac{1}{2}\right)} = \frac{128}{4} = 32$
The answer is $32$.
All you had to do is to plug in the numbers for the letters (for example plug in $8$ for $a$ in the original expression and so on) and solve it.
