$0.8÷1.6=0.5=50\%$
$25÷500=0.05=5\%$

答案： 0.625 62.5；0.5 50；0.05 5

1. $\frac {8}{25}×\frac {5}{64}=$$\frac{1}{40}$ $\frac {4}{15}÷\frac {20}{9}=$$\frac{3}{25}$ $3÷8= $37.5%
$\frac {14}{15}÷21=$$\frac{2}{45}$ $\frac {3}{16}×\frac {4}{9}=$$\frac{1}{12}$ $0.6÷15= $4%
$\frac {4}{5}×\frac {7}{10}=$$\frac{14}{25}$ $\frac {7}{9}÷\frac {5}{11}=$$\frac{77}{45}$ $3÷25= $12%
$\frac {4}{21}÷\frac {6}{7}=$$\frac{2}{9}$ $\frac {3}{10}-\frac {3}{20}=$$\frac{3}{20}$ $24÷200= $12%
$\frac {1}{6}+\frac {3}{16}=$$\frac{17}{48}$ $\frac {13}{30}÷\frac {39}{40}=$$\frac{4}{9}$ $20÷60\approx $33.3%
$\frac {7}{12}×\frac {3}{14}=$$\frac{1}{8}$ $\frac {8}{25}×\frac {15}{64}=$$\frac{3}{40}$ $2.4÷1.2= $200%

答案： 1. $\frac{1}{40}$ $\frac{3}{25}$ 37.5；$\frac{2}{45}$ $\frac{1}{12}$ 4；$\frac{14}{25}$ $\frac{77}{45}$ 12；$\frac{2}{9}$ $\frac{3}{20}$ 12；$\frac{17}{48}$ $\frac{4}{9}$ 33.3；$\frac{1}{8}$ $\frac{3}{40}$ 200
