10.34+2.78+1.34简便计算
10.34+2.78+1.34简便计算=10.34+1.34+2.78=11.68+2.78=14.46
7.92+(14.87 - 8.49)有没有简便算法?
7.92+(14.87-8.49)=7.92+6.38=8+6.3=14.3
54.7 - 45.3÷15 求简便算法 要详细过程 谢谢
54.7-45.3÷15=54.7-45.3÷(3*5)=54.7-45.3÷3÷5=54.7-15.1÷5=54.7-3.02=51.68
30.2*0.61有没有简便算法
30.2*0.61=30x0.61+0.2x0.61=18.3+0.122=18.422
简便运算48.4+2.78+5.16 - 0.48
解:48.4+2.78+5.16-0.48=48.4+(2.78-0.48)+5.16=48.4+2.3+5.16=50.7+5.16=55.86
45.4+54.6/0.42有没有简便算法
45.4+54.6÷0.42=45.4+54.6÷0.6÷0.7=45.4+91÷0.7=45.4+130=175.4
