64x101用乘法分配律计算

=64*(100+1)=64*100+64=6400+64=6464

101*24=(100+1)*24=100*24+24=2400+24=2424

101X64-64X1(101-1)X64

93*100+93*1=9393

101*101-101=101*101-101*1=101*(101-1)=101*100=10100

0.48*101 =0.48*(100+1) =0.48*100+0.48*1 =48+0.48 =48.48

原式=38x(100+1)=38x100+38x1=3800+38=3838

应该用:乘法分配律计算65x101=65*(100+1)=65*100+65=6500+65=6565

乘法分配率:a(b+c)=ab+ac.解:46X101=46X(100+1)=46X100+46X1=4600+46=4646.

101x28=100x28+1x28=2828
