答案：

解方程。
$x:0.4 = 0.3:0.8$ $20:x = \frac{2}{3}:\frac{4}{5}$ $6.5:x = 3.25:4$
$x = $ $x = $ $x = $
$1.5:\frac{3}{4} = 0.36:x$ $\frac{5}{8}:x = \frac{1}{10}:6$ $x:24 = \frac{3}{8}:\frac{9}{10}$
$x = $ $x = $ $x = $
$x:0.8 = 4:\frac{1}{3}$ $\frac{8}{13}:x = \frac{2}{13}:2$ $0.2:\frac{3}{10} = x:3$
$x = $ $x = $ $x = $
