7.2×2.18-72%×11.8 简便运算
7.2×2.18-72%×11.8 简便运算
7.2×2.18-72%×11.8
=7.2×2.18-0.72×11.8
=7.2×(2.18-1.18)
=7.2
7.2×2.18-72%×11.8
=7.2×1.18+7.2-7.2×1.18
=7.2
7.2×2.18-72%×11.8=0.72×21.8-0.72×11.8=0.72×(21.8-11.8)=0.72×10=7.2
7.2×2.18-72%×11.8
=7.2×2.18-0.72×11.8
=7.2×2.18-7.2×1.18
=7.2×(2.18-1.18)
=7.2×1
=7.2
7.2×2.18-72%×11.8
＝7.2×2.18-7.2×1.18
=7.2×（2.18-1.18）
=7.2×1
=7.2
