0.46十9.6÷0.32用简算

0.46十9.6÷0.32 =0.46十9.6÷0.32 =0.46+30 =30.46

呵呵 首先请确定信号源是标准的才行。你用什么仪器做标准来比对呢?

=4.6×9.9+4.6×0.1 =4.6×(9.9+0.1) =4.6×10 =46

不能简便的,下面哪一个你自己看一下。 0.46+9.6÷0.32 =0.46+30 =30.46 (0.46+9.6)÷0.32 =10.6÷0.32 =33.125

(1)2.9+0.46+7.1+0.54=(2.9+7.1)+(0.46+0.54)=10+1=11(2)27.6-11.31-5.69=27.6-(11.31+5.69)=27.6-17=10.6(3)3.6×99=3.6×(100-1)=3.6×100-3.6=360-3.6=356.4(4)32×2.5×12.5=8×4×2.5×12.5=(8×12.5)×(4×2.5)=100×10=1000(5)...
