9÷0.125
=(9×8)÷(0.125×8)
=72÷1
=72
25.25×0.65×4÷0.65
=(25.25×4)×(0.65÷0.65)
=101×1
=101
0.93×1.01
=0.93×(1+0.01)
=0.93×1+0.93×0.01
=0.93+0.0093
=0.9393
6.24-3.34-2.66
=6.24-(3.34+2.66)
=6.24-6
=0.24
0.485×102-48.5
=0.485×(100+2)-48.5
=0.485×100+0.485×2-48.5
=48.5-48.5+0.97
=0.97
4.4+4.4×12+13×5.6
=4.4×(1+12)+13×5.6
=4.4×13+13×5.6
=13×(4.4+5.6)
=13×10
=130
