0.125x8竖式计算

(1.25-0.125)x8=1.28*8-0.125*8=10-1=9

请参考图片答案.

巧妙计算0.125*0.125*0.125*0.125*8*8*8*8*8=(0.125x8)x(0.125x8)x(0.125x8)x(0.125x8)=1x1x1x1=1

26*(0.125*8)=26*1=26

你好:0.125=1/80.125x8=1/8x8=1你好:0.125x8=(0.1+0.02+0.005)x8=0.1x8+0.02x8+0.005x8=0.8+0.16+0.04=1

1.45*8=1.45* 8=11.6

0.12588简便计算=0.125x8x11=1x11=110.125x88=0.125x(80+8)=0.125x80+0.125x8=10+1=11

解答如下:简便计算的思路是,首先计算0.125X8,然后再乘以2.5即可0.125x2.5x8=(0.125X8)X2.5=1X2.5=2.5

恩恩 是等于64化成8000/125

=37*(0.125*8)=37*1=37
