【解析】

试题分析:根据整数、分数、小数的加减乘除计算的方法进行计算,能简算的要简算.

解:

1.8+0.5=2.3, 2.5﹣0.1=2.4, 4.8﹣0.2=4.6, 74+71=145,

48+10=58, 24÷12=2, 68÷0.68=100, 94.7÷0.1=947,

61.8÷0.6=103, 0.8×6.7=5.36, 3÷8=0.375, 0.12×3=0.36,

32=9, 8.2﹣2.8=5.4 3.5÷0.7=5, =

==, 5.3+0.5=5.8, 46+18=64,

8.5﹣1.5=7, 69+10=79, 28.8+0.4=29.2, 40.5÷0.5=81,

92.7÷0.3=309, 0.5×1.3=0.65, 16×0.5=8, 4.4+0.1=4.5,

6.1﹣0.1=6, 3.3+0.6=3.9, 33.2÷0.4=83, 1÷0.25=4,

1.5×4=6, 6.5+1.35=7.85, 1.3﹣1.2=0.1, =

==, 5.7﹣1.7=4, 0.35+0.75=1.1,

0.2×1.1=0.22, 1.6÷0.4=4, 10÷4=2.5, 3.4÷0.2=17,

52÷13=4, 57÷19=3, 3.7﹣0.8=2.9, 29+92=121,

8.2+0.7=8.9, 6.5﹣5.6=0.9, 4.8÷0.3=16, 33=27,

1.25×8=10, ===

2.1÷0.3=7, 3.2×3=9.6, 2.8﹣1.8=1, 0.9×6.2=5.58.

故答案为:2.3,2.4,4.6,145,58,2,100,947,103,5.36,0.375,0.36,9,5.4,5,,5.6,64,7,79,29.2,81,309,0.65,8,4.5,6,3.9,83,4,6,7.85,0.1,,4,1.1,0.22,4,2.5,17,4,3,2.9,121,8.9,0.9,16,27,10,,7,9.6,1,5.58.
