Б)
$\frac{3}{8}*5+\frac{5}{56}-\frac{1}{7}:\frac{1}{5}=\frac{15}{8}+\frac{5}{56}-\frac{1}{7}*5=\frac{105}{56}+\frac{5}{56}-\frac{5}{7}=\frac{110}{56}-\frac{40}{56}=1,25$ ;

г)
$\frac{4}{5}:\frac{5}{8}-\frac{4}{5}*\frac{24}{25}+\frac{1}{25}:\frac{5}{4}=\frac{4}{5}*\frac{8}{5}-\frac{4}{5}*\frac{24}{25}+\frac{1}{25}*\frac{4}{5}=\frac{4}{5}(\frac{8}{5}-\frac{24}{25}+\frac{1}{25})=\\\frac{4}{5}(\frac{40}{25}-\frac{23}{25})=\frac{4}{5}*\frac{17}{25}=\frac{68}{125}$ .
