When x=1/2, what is the value of 8x-3 over x?

Taya2010 [7]

$\frac{8( \frac{1}{2}) - 3 } { \frac{1}{2} }$
$\frac{(8 \times \frac{1}{2}) - 3 }{ \frac{1}{2} } = \frac{4 - 3}{ \frac{1}{2} }$
Because half of 8 is 4

$\frac{1}{ \frac{1}{2} } = \frac{1 \times 2}{1 \times 1} = 2$
Divide 1 by 1/2 or .5... 1 becomes 1/1 and 1/2 is flipped to 2/1, then multiply
