Answer 1

3.85*2.6+1.5*0.26-0.125*16*0.5

=2.6*(3.85+0.15)-0.125*8*2*0.5

=2.6*4-1

=10.4-1

=9.4

请参考

Answer 2

3.85X2.6+1.5x0.26一0.125X16X0.5
=2.6x(3.85-0.15)一0.125X8x2X0.5
=2.6x3.7-1x1
=9.62-1
=8.62

Answer 3

3.85X2.6+1.5x0.26-0.125X16X0.5
＝3.85×2.6+1.5×0.26×10÷10-0.125×4×4×0.5
＝3.85×2.6+(1.5÷10)×(0.26×10)-0.5×2
＝2.6×(3.85+0.15)-1
＝2.6×4-1
＝9.4
希望能帮到你。

Answer 4

3.85*2.6+1.5*0.26-0.125*16*0.5
=38.5*0.26+1.5*0.26-0.125*16*0.5
=(38.5+1.5)*0.26-0.125*(8*2)*0.5
=40*0.26-1*1
=9.6-1
=8.6
