Answer 1

$frac{0.05}{ frac{1}{7} - 0.125 } + frac{21}{6} = 6.3$

$1) frac{1}{7} - 0.125 = frac{1}{7} - frac{125}{1000} = frac{1000 - 875}{7000} = frac{125}{7000} = frac{1}{56}$

$2) 0.05 / frac{1}{56} = frac{5}{100} / frac{1}{56} = frac{5}{100} * frac{56}{1} = frac{280}{100} = 2 frac{80}{100} = 2 frac{4}{5}$

$3) 2 frac{4}{5} + frac{21}{6} = frac{14}{5} + frac{21}{6} = frac{6*14}{6*5} + frac{5*21}{5*6} = frac{84+105}{30} = frac{189}{30} = 6 frac{9}{30} = 6 frac{3}{10} = 6.3$
