2.5÷$\frac{1}{4}=$ $\frac{5}{6}÷15 =$ $\frac{0.5}{(\ \ \ \ \ )}=\frac{1}{5}$ 9×4 = ( )×3

答案： 10 $\frac{1}{18}$ 2.5 12

0.5³ = 0.24×0.5 = $\frac{3}{8}=\frac{15}{(\ \ \ \ \ )}$ 32×( ) = 4×8
70 - 46 = 12.5×8% = $\frac{1.5}{(\ \ \ \ \ )}=\frac{45}{90}$ ( )×4 = 1.6×5
$\frac{1}{7}-\frac{1}{8}=$ 3.6 + 6.4 = $\frac{5}{(\ \ \ \ \ )}=\frac{12}{6}$ 72×( ) = 9×32
