[________-(5.5+8.1)]×4.5=44.1136÷[________-(4.8-2.6)]=27.2.

23.4    7.2
分析:將空格當(dāng)作未知數(shù),根據(jù)等式的性質(zhì)解方程即可求解.
解答:令空格為x,則
[x-(5.5+8.1)]×4.5=44.1,
x-(5.5+8.1)=9.8,
x-13.6=9.8,
x=23.4;

令空格為x,則
136÷[x-(4.8-2.6)]=27.2,
x-(4.8-2.6)=5,
x-2.2=5,
x=7.2.
故答案為:23.4;7.2.
點(diǎn)評(píng):考查了解方程,本題關(guān)鍵是將空格當(dāng)作未知數(shù).
