Answer 1

9-4.8÷6×0.5
=9-0.8×0.5
=9-0.4
=8.6
（1.4×0.3+2.46）1.8
=（0.42+2.46）÷1.8
=2.88÷1.8
=1.6
（2.5÷2+2÷2.5）×0.4
=（1.25+0.8）×0.4
=1.25×0.4+0.8×0.4
=0.5+0.32
=0.82
3.71+3.71×7.4-8.4×3.71
=3.71×（1+7.4-8.4）
=3.71×0
=0
1.2+8.8×1.25
=1.2+1.1×（8×1.25）
=1.2+1.1×10
=1.1+11
=12.1
16.2÷[64.8-（51.3-2.7）]
=16.2÷[64.8-48.6]
=16.2÷16.2
=1
