二、计算下面各题。
$(1 - 0.5)\times(4.12 + 0.9)$ $2.5\times[(2.35 - 1.66)\div0.3]$
$44.1\div[5\times(6.5 - 5.6)]$ $92\times0.6 - 18.6\div6$
$(0.9 - 0.15\times0.6)\div0.01$ $76.81 - 3.4\times(7.5 - 6.05)$
$(1 - 0.5)\times(4.12 + 0.9)$ $2.5\times[(2.35 - 1.66)\div0.3]$
$44.1\div[5\times(6.5 - 5.6)]$ $92\times0.6 - 18.6\div6$
$(0.9 - 0.15\times0.6)\div0.01$ $76.81 - 3.4\times(7.5 - 6.05)$
答案:
2.51 5.75 9.8
