用简便方法计算：8.8÷0.25 3.1÷0.125 34.2×5.6+658×0.56

8.8÷0.25
=8.8×4
=8×4+0.8×4
=32+3.2
=35.2
3.1÷0.125
=3.1×8
=24.8
34.2×5.6+658×0.56
=342×0.56+658×0.56
=(342+658)×0.56
=1000×0.56
=560前面两题好像不对哎怎么不对?对对 我看错了 嘿嘿对了还不采纳?*v*还有个问题在问题补充里2. 计算11/24×67/30×182/13×265/8×1211/24×6=11/47/30×18=21/52/13×26=45/8×12=15/2
