问题描述:

简算:1.(336699-3366.99)/(112233-1122.33) 2.137*136分之135-135*136分之1

1.(336699-3366.99)/(112233-1122.33)
=(3*112233-3*1122.33)/(112233-1122.33)
=3*(112233-1122.33)/(112233-1122.33)
=3
2.137*135/136-135*1/136
=135/136*(137-1)
=135

1:原式=100/100=1
2:137×135/136-135×1/136
=135/136×(137-1)
=135/136 ×136
=135

1.(336699-3366.99)/(112233-1122.33)
=3(112233-1122.33)/(112233-1122.33)
=3
2.137*136分之135-135*136分之1
=135/136(137-1)
=135/136*136
=135
