Question

1/2 (1/5 + 1/2 . 1/3) - 1/5 . (1/6 + 1/2 . 1/5)

Answer 1

$\frac{1}{2}\times( \frac{1}{5}+ \frac{1}{2}\times \frac{1}{3} )- \frac{1}{5}\times( \frac{1}{6}+ \frac{1}{2}\times \frac{1}{5} ) \\ \\ \frac{1}{2}\times( \frac{1}{5}+ \frac{1}{6} )- \frac{1}{5}\times( \frac{1}{6}+ \frac{1}{10} ) \\ \\ \frac{1}{2}\times \frac{11}{30}- \frac{1}{5}\times \frac{8}{30} \\ \\ \frac{11}{60}- \frac{8}{150} = \frac{55-16}{300} = \frac{39}{300} = \frac{13}{100}$
