小学六年级一课四练

(1)4.83×0.59+0.41×1.59-0.324×5.9=4.83*0.59+0.41*0.59+0.41-3.24*0.59
=(4.83+0.41-3.24)*0.59+(1-0.59)=1+(4.83+0.41-3.24-1)*0.59=1+(5.24-3.24-1)*0.59=1.59
(2)0.5*236*119=118*119=(120-2)(120-1)=120*120-3*120+2=14400-360+2=14402-360=14042

1）4.83×0.59+0.41×1.59-0.324×5.9
=4.83*0.59+0.41*(1+0.59)-0.327*10*0.59
=4.83*0.59+0.41+0.41*0.59-3.27*0.59
=(4.83+0.41-3.27)*0.59+0.41
=1.5723
第二题0.5×236×——
119没看懂你的意思。

1.(4.83-3.24)*0.59+0.41*1.59=0.59*1.59+0.41*1.59=(0.59+0.41)*1.59=1.59

2.题目不全吧!
