9÷0.125
=9×8
=72
25.25×0.65×4÷0.65
=25.25×4×(0.65÷0.65)
=(25+0.25)×4×1
=25×4+0.25×4
=100+1
=101
0.93×1.01
=0.93×(1+0.01)
=0.93×1+0.93×0.01
=0.93+0.0093
=0.9393
6.24-3.32-2.66
=6.24-(3.32+2.66)
=6.24-5.98
=6.24-(6-0.02)
=6.24-6+0.02
=0.24+0.02
=0.26
0.485×102-48.5
=0.485×(100+2)-0.485×100
=0.485×100+0.485×2-0.485×100
=0.485×2
=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
