一、口算。
78 + 35 = 4.7÷0.5 = 5 - 2.08 =
15.7÷3.14 = 5.3 - 2.5 = 5.87 + 3.9 =
0.96÷12％ = 607 - 499 = 48÷0.24 =
0.28 + 0.8 = 32.4×0.5 = 75％×24％ =
1.47÷7 = 12.5÷5％ = $\frac{4}{15}-\frac{8}{35}=$
$\frac{7}{8}-\frac{1}{8}=$ $\frac{8}{5}÷\frac{2}{15}=$ $\frac{3}{4}×\frac{8}{9}=$
$\frac{7}{13}×\frac{39}{35}=$ $\frac{4}{9}+\frac{1}{6}=$ $\frac{5}{12}+\frac{7}{5}=$
$\frac{5}{6}÷\frac{11}{12}=$ $\frac{1}{6}×\frac{4}{33}=$ 0.125 + $\frac{3}{8}=$
1 - 0.71 = 314÷3.14 = 1.43×10％ =
$\frac{12}{25}×\frac{5}{3}=$ 3÷5 = $\frac{8}{7}×7=$

二、计算下面各题，怎样简便就怎样计算。
15.2×0.4 - 0.25÷0.5 $\frac{13}{18}÷9+\frac{5}{18}×\frac{1}{9}$ $\frac{9}{10}×[75％÷(25％ + 20％)]$

答案： 5.58@@$\frac{1}{9}$@@$\frac{3}{2}$
