4.81×99
=4.81×(100-1)
=4.81×100-4.81
=481-4.81
=476.19
祝,好好学习
答
把99变成(100-1)
4.81*(100-1)
=4.81*100-4.81*1
=481-4.81
=476.19
答
本题把99变成100-1采用乘法对加法的分配律得,
4.81×99
=4.81×(100-1)
=4.81×100-4.81
=481-4.81
=476.19
答
4.81×99
=4.81×(100-1)
=4.81×100-4.81
=481-4.81
=476.19
答
4.81×(100-1)
=4.81×100-4.81
=481-4.81
