Question

Which expression is equivalent to 1/8x−1/2 ? *
1/8(x-4) -1/8(x-4) 1/8(x-1/2) 1/8(x-1/4)

Answer 1

The answer would be $\frac{1}{8}(x-4)$.

Using distribution, you will know the answer. Let's take the first option and show you how it matches the given:

$\frac{1}{8} (x-4)$

Distribute 1/8 to each term in the parenthesis and multiply. 

$(\frac{1}{8} )(x) - (\frac{1}{8})(4)$
$\frac{1}{8}x - \frac{4}{8}$ Simplify the fractions
$\frac{1}{8}x - \frac{1}{2}$
