答案
| （1）9.37﹣4.7+0.63 | |
| =（9.37+0.63）﹣4.7 | |
| =10﹣4.7 | |
| =5.3 | （2）4.05÷0.81+4.2 |
| =5+4.2 | |
| =9.2 | （3）0.125×32×0.25 |
| =0.125×8×4×0.25 | |
| =（0.125×8）×（4×0.25） | |
| =1×1 | |
| =1 | |
| （4）4.8×99+4.8 |
=4.8×（99+1）
=4.8×100
=480
=5.11﹣（1.25+0.75）
=5.11﹣2
=3.11
=1.76﹣[1÷0.8]
=1.76﹣1.25
=0.51
