一、口算。
$0.6\div0.15=$ $\frac{1}{5}+\frac{7}{15}=$ $84\times\frac{5}{7}=$
$368 + 22=$ $\frac{9}{7}\times\frac{2}{3}=$ $\frac{10}{21}\div\frac{2}{3}=$
$\frac{4}{7}\div\frac{2}{5}=$ $\frac{7}{8}\div\frac{1}{12}=$ $1 - 0.72\%=$
$20\times6.2=$ $20\% + 34.5\%=$ $\frac{3}{7}\div0.3=$
$\frac{7}{8}\div\frac{5}{16}=$ $\frac{2}{5}-\frac{1}{8}=$ $\frac{14}{15}\times\frac{5}{21}=$
$32\times75\%=$ $\frac{5}{8}\times40\%=$ $\frac{4}{5}+\frac{7}{20}=$
$\frac{5}{8}-\frac{1}{15}=$ $0.75 + 0.375=$ $\frac{2}{13}\times\frac{39}{40}=$
$0.2 + 0.88=$ $\frac{4}{3}-\frac{1}{2}=$ $9 - 0.87=$
$0.8\div0.2=$ $20.8\% - 8\%=$ $18+\frac{1}{5}=$
$4-\frac{5}{3}=$ $\frac{5}{22}\times4=$ $5.8 + 5.2=$

答案： 4@@$\frac{2}{3}$@@60@@390@@$\frac{6}{7}$@@$\frac{5}{7}$@@$\frac{10}{7}$@@$\frac{21}{2}$@@99.28%@@124@@54.5%@@$\frac{10}{7}$@@$\frac{14}{5}$@@$\frac{11}{40}$@@$\frac{2}{9}$@@24@@$\frac{1}{4}$@@$\frac{23}{20}$@@$\frac{67}{120}$@@1.125@@$\frac{3}{20}$@@1.08@@$\frac{5}{6}$@@8.13@@4@@12.8%@@$18\frac{1}{5}$@@$\frac{7}{3}$@@$\frac{10}{11}$@@11

二、解比例。
$x:17=\frac{4}{3.4}$ $\frac{x}{7}=\frac{1.2}{21}$ $\frac{1}{20}:\frac{1}{5}=x:\frac{1}{4}$

答案： $x = 20$@@$x = 0.4$@@$x=\frac{1}{16}$
