101 2.4简算

101x2.4=(100+1)x2.4=100x2.4+1x2.4=240+2.4=242.4 解题思路:运用乘法分配律.希望能帮到你!

101*2.4 =100*2.4+1*2.4 =240+2.4 =242.4

12.4乘以101-2.4=12.4x(101-1)=12.4x100=1240

101x2.4=(100+1)x2.4=100x2.4+1x2.4=240+2.4=242.4

12.4*101-2.4=12.4*101-2.4-10+10 =12.4*101-(2.4+10)+10 =12.4*101-12.4+10 =12.4*(101-1)+10 =12.4*100+10 =1240+10 =1250

101*2.4*6.7*0.1=(100+1)*2.4*0.67=67*2.4+2.4*0.67=67*2.4+67*0.024=67*(2+0.4+0.02+0.004)=162.408 但愿帮到你,望采纳!

=100*83+1*83=8300+83=8383

2.4*101-2.4的脱式计算2.4*101-2.4=2.4*(101-1)=2.4*100=240

101*1/5-1/5*21=1/5 *(101-21)=1/5 *80=16 4/3*2+4/3= 4/3*(2+1)= 4/3*3=4

105*2.4=(100+5)*2.4=100*2.4+5*2.4=240+12=252
