$frac{1}{4} + frac{1}{2} - frac{1}{8} = frac{2 + 4 - 1}{8} \ = frac{5}{8}$

$frac{4}{7} - frac{1}{4} div frac{1}{2} = frac{4}{7} - frac{1}{4} times 2 \ = frac{4}{7} - frac{1}{2} \ = frac{1}{14}$

$frac{2}{3} + frac{1}{7} div 0.6 = frac{2}{3} + frac{1}{7} div frac{3}{5} \ = frac{2}{3} + frac{1}{7} times frac{5}{3} \ = frac{2}{3} + frac{5}{21} \ = frac{19}{21}$
