一、口算。
$6.02 - 5.94 = $0.08 $3.4×20 = $68 $0.63÷9 = $0.07
$0.7×0.8 = $0.56 $3.5÷0.7 = $5 $3.2×0.4 = $1.28
$1.72 - 0.4 = $1.32 $0.25×4 = $1 $4.9÷0.07 = $70
$3.05×100 = $305 $6.45 + 5.5 = $11.95 $0.83 - 0.62 = $0.21
$0.63÷0.7 = $0.9 $5.6÷1.4 = $4 $4.4 + 1.06 = $5.46
$3×4.2 = $12.6 $6 - 0.6 = $5.4 $0.125÷0.25 = $0.5
$\frac{2}{3} - \frac{1}{4} = $$\frac{5}{12}$ $\frac{1}{3} + \frac{1}{8} = $$\frac{11}{24}$ $\frac{7}{8} - \frac{3}{10} = $$\frac{23}{40}$
$\frac{8}{9} + \frac{1}{6} = $$\frac{19}{18}$ $\frac{11}{15} - \frac{8}{15} = $$\frac{1}{5}$ $\frac{7}{30} + \frac{2}{5} = $$\frac{19}{30}$

答案： 0.08 68 0.07 0.56 5 1.28 1.32 1 70 305 11.95 0.21 0.9 4 5.46 12.6 5.4 0.5 $\frac{5}{12}$ $\frac{11}{24}$ $\frac{23}{40}$ $\frac{19}{18}$ $\frac{1}{5}$ $\frac{19}{30}$

二、计算下面各题,怎样简便就怎样计算。
$1.08÷(3.94 + 34.3×0.2)$ $548×0.52 + 452×0.52$
$21.28 - 21.28÷7.6 + 2.4$ $17.5 - 2.5×5 - 2.5$

答案： 0.1 520 20.88 2.5
