分析:根據(jù)題意,分別求出各個選擇中的結果,然后再進一步解答.
解答:A、224+(112+56),
=224+168,
=392;
224+112+56,
=336+56,
=392;
所以,224+(112+56)=224+112+56;
B、224-(112-56),
=224-56,
=168;
224-112+56,
=112+56,
=168;
所以,224-(112-56)=224-112+56;
C、224×(112×56),
=224×6272,
=1404928;
224×112×56,
=25088×56,
=1404928;
所以,224×(112×56)=224×112×56;
D、224÷(112÷56),
=224÷2,
=112;
224÷112×56,
=2×56,
=112;
所以,224÷(112÷56)224÷112×56;
E、224÷(112÷56),
=224÷2,
=112;
224÷112÷56,
=2÷56,
=
;
所以,224÷(112÷56)≠224÷112÷56.
故選:E.
點評:關鍵是求出每個選項中結果,然后再進一步解答.
