Question

0.655×112-1.2×6.55的简便运算是什么？

Answer 1

由题意得：
0.655x112-1.2x6.55
=0.655x(10x11.2)-1.2x6.55
=0.655x10x11.2-1.2x6.55
=6.55x11.2-1.2x6.55
=6.55x(11.2-1.2)
=6.55x10
=65.5

Answer 2

你好，根据你的题意，这道题我认为应该这样做最简便
0.655×112-1.2×6.55
=0.655×112-12×0.655
=0.655×(112-12)
=0.655×100
=65.5
以上仅供参考，希望能对你有所帮助

Answer 3

0.655x112-1.2x6.55
=(0.655x10)x(112/10)-1.2x6.55
=6.55x11.2-1.2x6.55
=6.55x(11.2-1.2)
=6.55x10
=65.5

Answer 4

0.655×112－1.2×6.55=6.55×11.2－1.2×6.55=6.55×(11.2－1.2)=6.55×10=65.5

Answer 5

原式=6.55×11.2_1.2×6.55=6.55×（11.2_1.2）=6.55×10=65.5
