Question

Calculati: 1\2-(1\4-1\8)=

Answer 1

1\2-(0.25-0.125)=1\2-0.125
                      =0.5-0.125
                     =0.375

Answer 2

$\displaystyle \frac{1}{2} -\left( \frac{1}{4} - \frac{1}{8} \right )= \frac{1}{2} - \left( \frac{2}{8} - \frac{1}{8} \right )= \frac{1}{2} - \frac{1}{8} = \frac{4}{8} - \frac{1}{8} = \frac{3}{8}$
