0.27 + 4.33 = 0.36÷6 = $\frac{18}{3}=\frac{(\ \ \ \ )}{1}$ ( )×1 = 8×2
1 - 0.08 = 9.3×0.3 = $\frac{22}{11}=\frac{(\ \ \ \ )}{5}$ 7×( ) = 35×4
1.1 - 0.11 = 10.4÷8 = $\frac{(\ \ \ \ )}{6}=\frac{2}{8}$ ( )×3 = 15×8
9.9 + 0.01 = 0.72÷18 = $\frac{4}{(\ \ \ \ )}=\frac{20}{10}$ 2.4×2 = 0.6×( )
3.5 + 5.5 = 1.28÷0.4 = $\frac{3.5}{5}=\frac{1.4}{(\ \ \ \ )}$ 1.5×4 = 0.5×( )
12.58 + 0.2 = 0÷9.9 = $\frac{0.4}{0.5}=\frac{(\ \ \ \ )}{25}$ 18×6 = 9×( )

答案： 4.6 0.06 6 16
0.92 2.79 10 20
0.99 1.3 1.5 40
9.91 0.04 2 8
9 3.2 2 12
12.78 0 20 12

0.25 : $\frac{3}{4}=\frac{2}{3}:x$ $\frac{1}{2}x-\frac{1}{3}x = 6$ $x + 0.25x = 8.5$
$(x - 3.6)×4 = 32.8$ 20 - 30%$x$ = 8 $x:1.2=\frac{5}{4}$

答案： $x = 2$ $x = 36$ $x = 6.8$
$x = 11.8$ $x = 40$ $x = 1.5$
