1厘米=1cm 0.4cm=0.4*1=0.4厘米 0.5cm=0.5*1=0.5厘米 0.4

0.4X0.5=0.2MM 望采纳

∵ 被乘数为45,乘积的百位数和十位数为0,个位数为5的千位数中,乘数仅限于下列各数: 101

5/6x0.4=5/6x2/5(约分后)=1/3

4-5乘a =4-5a

(0.4x+5)*0.8+0.4x+17=x0.72x+21=xx=21/0.28=3/0.04=3

解: 0.5乘以10的负4次方 =0.5x0.0001 =0.00005 =5乘以10的(-

解: 0.4*(5/2)=3/2*(2/3)=(0.2)*5=1.2*(5/6)=1

8x5=40 (6+2)x5 =8x5 =40
