答案
(1)(30-19.8) ×0.6+31.2 | |
=10.2×0.6+31.2 | |
=6.12+31.2 | |
=37.32 | (2)[10-(6+3.03)] ×1.01 |
=[10-9.03]×1.01 | |
=0.97×1.01 | |
=0.9797 | |
(3)73.6 ×27+73.6 ×73 | |
=73.6×(27+73) | |
=73.6×100 | |
=7360 |
=49.2-0.25-8.75
=49.2-(0.25+8.75)
=49.2-9
=40.2
(5)(291-38 ×3.5-35.5) ÷3.5
=(291-133-35.5)÷3.5
=122.5÷3.5
=35
=(12.5×0.8)×(0.4×250)×0.56
=10×100×0.56
=560
