88.8×3.2+44点4×3.6怎么简便计算? -
88.8×3.2+44.4×3.6 =88.8x3.2 + 44.4x2x1.8 =88.8x3.2+88.8x1.8 =88.8x(3.2+1.8)=88.8x5 =44.4x2x5 =44.4x10 =444
88.8×389 +44.4×222 =44.4x2x389+44.4x222 =44.4x（778+222）44.4x1000 =44400
88.8×3.2+44.4×3.6 =88.8x3.2 + 44.4x2x1.8 =88.8x3.2+88.8x1.8 =88.8x(3.2+1.8)=88.8x5 =44.4x2x5 =44.4x10 =444
88.8×389 +44.4×222 =44.4x2x389+44.4x222 =44.4x（778+222）44.4x1000 =44400
88.8×5.6+44.4×8.8 =88.8×5.6+44.4×2×4.4 =88.8×5.6+88.8×4.4 =88.8×(5.6+4.4)=88.8×10 =888
计算：44.4x44+28x88.8 =88.8x22+28x88.8 =88.8x(22+28)=88.8x50 =4440

12.5x88.8(可以想出几种简算方法)? -
12.5x88.8通过对试题的分析，我们可以发现12.5乘以8为整数，所以原式子可以简算为12.5乘以80+12.5乘以8+12.5乘以0.8=1110
88.8×8+222×1.8 =88.8×8+22.2×8+222 =111×8+222 =888+222 =1110 所以这个可以通过简便运算得到，答案是1110
