一、口算。
$20×73\%=$ $216 - 106=$ $0.25×400=$
$1.24×4=$ $3.9×20\%=$ $5.6 + 70\%=$
$1÷40\%=$ $7.86÷2=$ $0.58×50\%=$
$40×70\%=$ $428 - 99=$ $3÷30\%=$
$10÷\frac{5}{6}=$ $0.8^{2}=$ $\frac{8}{13}÷\frac{4}{39}=$
$\frac{3}{4}×\frac{12}{7}=$ $34×\frac{2}{51}=$ $\frac{2}{3}+\frac{1}{9}=$
$\frac{3}{8}-\frac{3}{11}=$ $14.4÷0.16=$ $\frac{19}{21}-\frac{4}{7}=$
$\frac{5}{7}÷\frac{10}{21}=$ $\frac{1}{5}+\frac{3}{7}=$ $\frac{1}{2}÷2=$
$45×\frac{4}{5}=$ $\frac{1}{2}-0.5=$ $\frac{20}{21}÷\frac{4}{3}=$
$\frac{3}{2}-\frac{2}{5}=$ $\frac{5}{6}÷\frac{5}{18}=$ $117.5\% - 1.5\%=$

答案： 14.6@@110@@100@@4.96@@0.78@@6.3@@2.5@@3.93@@0.29@@28@@329@@10@@12@@0.64@@6@@$\frac{9}{7}$@@$\frac{4}{3}$@@$\frac{7}{9}$@@$\frac{9}{88}$@@90@@$\frac{1}{3}$@@$\frac{3}{2}$@@$\frac{22}{35}$@@$\frac{1}{4}$@@36@@0@@$\frac{5}{7}$@@3@@1.16

二、计算下面各题，怎样简便就怎样计算。
$52.5 - 4.72×1.5 + 11.2$ $12.5\%×5.8+\frac{1}{8}×420$ $13×(\frac{1}{13}+\frac{4}{15})×15$

答案： 56.62@@53.225@@67

一、口算。
$0.8×45=$ $\frac{7}{16}+\frac{3}{8}=$ $\frac{5}{9}×\frac{3}{5}=$
$\frac{7}{15}+\frac{3}{5}=$ $\frac{3}{20}÷15=$ $\frac{7}{13}÷\frac{7}{3}=$
$\frac{3}{8}×0.24=$ $\frac{9}{13}-\frac{9}{26}=$ $0.38×5=$
$0.64÷0.5=$ $0.2 + 68\%=$ $3.14 + 0.8=$
$\frac{5}{4}-\frac{5}{7}=$ $\frac{6}{5}×\frac{6}{7}=$ $28.9 + 9=$
$9.1÷1.3=$ $9.6÷0.6=$ $\frac{15}{17}-\frac{1}{3}=$
$1.25×0.08=$ $\frac{7}{40}×\frac{8}{35}=$ $2.3÷10=$
$\frac{2}{3}+\frac{5}{6}=$ $\frac{5}{9}×\frac{1}{8}=$ $0.063 + 6.327=$
$\frac{5}{13}÷\frac{7}{26}=$ $72÷\frac{4}{5}=$ $\frac{3}{5}+\frac{1}{8}=$
$4 - 1.26=$ $6.3 - 6=$ $85÷20=$
