Answer 1

47.8-7.45+8.8
=40.35+8.8
=49.15

4.2*10.1
=4.2×10+4.2×0.1
=42+0.42
=42.42

0.125*88
=0.125*8*11
=1*11
=11

（201-11.28/2.4）*3.6
=201*3.6-11.28/2.4*3.6
=200*3.6+3.6-11.28×1.5
=723.6-16.92
=707.68

56.5*9.9+5.65
=5.65*99+5.65
=5.65*（99+1）
=5.65*100
=565

0.54*180/（300-255）
=0.54*180/45
=0.54*4
=2.16

（1.25-0.125）*8
=1.25*8-0.125*8
=10-1
=9

45/0.09/0.5
=90/0.09
=1000

3.6*0.99
=3.6*（1-0.01）
=3.6-0.0036
=3.564

17.8/（1.78*4）
=17.8/1.78/4
=10/4
=2.5
