$32$ $32$

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:

$\frac{4 a b}{8 c} \Rightarrow \frac{4 (8) (4)}{8 (\frac{1}{2})}$ $(4ab)/(8c) => (4(8)(4))/(8(1/2))$

Now we can solve the expression:

$\frac{4 (8) (4)}{8 (\frac{1}{2})} \Rightarrow \frac{(32) (4)}{4} \Rightarrow \frac{128}{4} \Rightarrow 32$ $(4(8)(4))/(8(1/2)) => ((32)(4))/(4) => 128/4 => 32$

Answer 2 · 2018-03-09T18:13:07

$\frac{4 (8) (4)}{8 (\frac{1}{2})} = \frac{128}{4} = 32$ $(4(8)(4)) / (8(1/2))= 128/4=32$

The answer is $32$ $32$ .

Explanation:

All you had to do is to plug in the numbers for the letters (for example plug in $8$ $8$ for $a$ $a$ in the original expression and so on) and solve it.
