如题所述
43×41/42+1/42
=41+41/42+1/42
=41+1
=42
在这可以通过把43拆成42+1,计算比较简便。

依据题意列式计算如下:
43×41/42+1/42
=42×41/42+1×41/42+1/42
=41+1/42×(41+1)
=41+1
=42
43×41/42+1/42
=42×41/42+1×41/42+1/42
=41+1/42×(41+1)
=41+1
=42

解:43x41/42+1/42
=1/42×(43×42+1)
=1/42×1807
=43又1/42
=1/42×(43×42+1)
=1/42×1807
=43又1/42

这道题可以这样子来进行计算的
42+1×42-1,等于42^2-1
然后42^2÷42-1/42+1/42=42
42+1×42-1,等于42^2-1
然后42^2÷42-1/42+1/42=42
