28×0.5= 0.18÷0.6= 1-0.47+0.53= 16.5×9+16.5=
3.6-3.6÷1.2= 1÷0.5= (6.9-6.9)×74.8= 15-9.4+0.6=
4.99-2.6-1.4= 12.5×3×8= 8.6÷8.6+8.6= 0.25×4÷0.25×4=
分析:根据整数、小数的加减乘除计算的方法进行计算,能简算的要简算.
解答:解:
28×0.5=14 0.18÷0.6=0.3 1-0.47+0.53=1.06 16.5×9+16.5=165
3.6-3.6÷1.2=0.6 1÷0.5=2 (6.9-6.9)×74.8=0 15-9.4+0.6=6.2
4.99-2.6-1.4=0.99 12.5×3×8=300 8.6÷8.6+8.6=9.6 0.25×4÷0.25×4=16
故答案为:14,0.3,1.06,165,0.6,2,0,6.2,0.99,300,9.6,16.
点评:计算时,要灵活运用所学的知识,快速准确的进行计算.
