4.12×35.7+3.57×47.6+8.88×64.3
=35.7×4.12+35.7×4.76+8.88×64.3
=35.7×（4.12+4.76）+8.88×64.3
=35.7×8.88+8.88×64.3
=8.88×（35.7+64.3）
=8.88×100
=888
=35.7×4.12+35.7×4.76+8.88×64.3
=35.7×（4.12+4.76）+8.88×64.3
=35.7×8.88+8.88×64.3
=8.88×（35.7+64.3）

原式：
4.12*35.7+35.7*4.76+8.88*64.3
=35.7*（4.12+4.76）+8.88*64.3
=35.7*8.88+8.88*64.3
=8.88*（35.7+64.3）
=8.88*100
=888
请采纳谢谢
