4.7*2.2+0.6*1.1简便计算
4.7*2.2+0.6*1.1简便计算
4.7*2.2+0.6*1.1简便计算
=4.7*2.2+0.3*2.2
=(4.7+0.3)*2.2
=5*2.2
=11
=4.7×1.1×2+0.6×1.1
=4.7*2*1.1+0.6*1.1
=(4.7*2+0.6)*1.1
=10*1.1=11
(4.7+2.2+1.1)+0.6
=4.7x2x1.1+0.6x1.1
=(9.4+0.6)x1.1
=10x1.1
=11
=4.7x2.2+0.3x2.2=(4.7+0.3)x2.2=5x2.2=11
9.4*1.1+0.6*1.1
=1.1(4.7*2+0.6)
=1.1(9.4+0.6)
=1.1*10
=11
