一、口算。
$64\%\div0.8 =$ $\frac{5}{6}×24\% =$ $\frac{4}{5}-\frac{1}{2}=$
$0.2 + 0.17 =$ $63\% - 0.6 =$ $\frac{3}{10}×\frac{1}{5}=$
$16\%\div\frac{2}{3}=$ $18\% + 72\% =$ $13.2 - 2.5 =$
$0.95 - 8\% =$ $0.56\div28\% =$ $0.5 + 0.55 =$
$26\div100\% =$ $5.8 + 2\% =$ $\frac{3}{5}×\frac{1}{2}=$
$75\% + 2.5\% =$ $0.8×1.5 =$ $375\div4 =$
$39\%×4 =$ $\frac{7}{20}\div\frac{2}{5}=$ $100\% - 29.8\% =$
$1 - 0.96 =$ $6.8 + 1.28 =$ $5\%\div25\% =$
$50×30\% =$ $70\%×20\% =$ $7.4\div0.2 =$
$\frac{3}{10}\div\frac{1}{2}=$ $35\% - 34.3\% =$ $\frac{3}{7}×\frac{5}{6}=$

答案： 0.8@@$\frac{1}{5}$@@$\frac{3}{10}$@@0.37@@0.03@@$\frac{3}{50}$@@$\frac{6}{25}$@@90%@@10.7@@0.87@@2@@1.05@@26@@5.82@@$\frac{3}{10}$@@77.5%@@1.2@@93.75@@1.56@@$\frac{7}{8}$@@70.2%@@0.04@@8.08@@$\frac{1}{5}$@@15@@0.14@@37@@$\frac{3}{5}$@@0.7%@@$\frac{5}{14}$

二、计算下面各题，怎样简便就怎样计算。
$1.68×99 + 1.68$ $\frac{16}{9}×\frac{10}{11}-\frac{7}{9}\div\frac{11}{10}$ $60\%\div[(\frac{7}{9}+\frac{1}{3})×\frac{3}{2}]$

答案： 168@@$\frac{10}{11}$@@$\frac{9}{25}$
