$\frac{1}{8} \times 4=$ $300 \times 7\% =$ $45\% \times 20=$ $1 \div \frac{7}{9}=$
$40\% \times 16=$ $20\% + 25\% =$ $0 \div \frac{5}{8}=$ $6 \div \frac{2}{3}=$
$\frac{5}{6} \div \frac{4}{6}=$ $1 - 37\% =$ $60 \div 6\% =$ $5 \times 60\% =$
$20 \times 33\% =$ $47 \times 2\% =$ $34 \times 10\% =$ $0 \times \frac{8}{11}=$
$55 \times 2\% =$ $\frac{3}{4} \times \frac{4}{3}=$ $5\% \times 16=$ $93 \div 31\% =$
$7.4 \div 37\% =$ $\frac{5}{9} \times \frac{(\ \ \ \ )}{(\ \ \ \ )}=1$ $\frac{1}{3} \times \frac{1}{5}=$ $62 \times 50\% =$

答案： $\frac{1}{2}$ 21 9 $\frac{9}{7}$
6.4 0.45 0 9
$\frac{5}{4}$ 0.63 1000 3
6.6 0.94 3.4 0
1.1 1 0.8 300
20 $\frac{9}{5}$ $\frac{1}{15}$ 31

$70\%x = 756$ $x - 54\%x = 9.2$ $x + 80\%x = 45$
$83 - 16\%x = 75$ $40\%x + 20 = 104$ $x - 39\%x = 122$

答案： $x = 1080$ $x = 20$ $x = 25$
$x = 50$ $x = 210$ $x = 200$
