Answer 1

分析：根據(jù)小數(shù)四則運(yùn)算的計(jì)算方法進(jìn)行計(jì)算．

解答：

解：5.6÷0.07=80	0.02×25=0.5	6÷1.2=5	2.5×0.6=1.5	12.5×8=100
0.02×0.1=0.002	6.3÷0.7=9	0.18+0.72=0.9	0.8×0.5=0.4	99+0.1﹦99.1
42=16	0.12=0.01	0.08×10=0.8	1÷0.125=8	1÷0.01=100
1-0.02=0.98	43×0.01﹦0.43	4.2÷2.1=2	1.8÷0.18=10	1.03-0.9=0.13

點(diǎn)評(píng)：本題綜合考查了學(xué)生小數(shù)四則運(yùn)算的計(jì)算能力，注意要細(xì)心．
