Question

7.62×0.18+8.2×0.762-76.2×0.1可不可以简便计算？

Answer 1

这个按道理是可以简便计算的呀，把中间的0.762变成7.62，8点二就变成0.82。后面的76.2就变成7.62。那么0.1就变成了一了。然后把7.62这个公因数提出来，括号里面就成了0.18加。0.82再加一。加完了以后再和前面的7.62相乘啊。

Answer 2

7.62×0.18+8.2×0.762-76.2×0.1
=7.62×0.18+8.2×0.1×7.62-7.62×10×0.1
=7.62×0.18+0.82×7.62-7.62×1
=7.62×(0.18+0.82-1)
=7.62×0
=0

Answer 3

7.62×0.18+8.2×0.762-76.2×0.1=7.62×0.18+0.82×7.62+7.62×1=7.62×（0.18+0.82+1）=7.62×2=15.24
计祘结果为15.24.

Answer 4

可以简便计算：
7.62X0.18+8.2X0.762-76.2X0.1
=7.62X0.18+0.82X7.62-7.62X1
=7.62X（0.18+0.82-1）
=7.62X0
=0

Answer 5

可以的，以7.62看成提取数，7.62*0.18+8.2/10*0.762*10-76.2/10*0.1*10=7.62*(0.18+0.82-1)=0
