简便计算:53.9×23.6 40.5

9.16x1.53-0.053x91.6 =9.16x1.53-0.53x9.16 =9.16x...

小数点后相同的项可以优先计算, 计算过程如下: 19.53+7.6-6.6-9.53 =(19.53...

9.16×1.53-0.053×91.6 =9.16×1.53-0.53×9.16 =9.16×(1...

(29×53)-(53×9) =53x(29-9) =53x20 =1060

用简便方法计算 54×53+53×54-54×9 =54x(53+53-9) =54x(100-3)...

9.53-x=6.28,只有一个未知数x的一元一次方程,移项合并同类项就可以求出x的值。 x=9....

53又9/17÷13 =52又26/17÷13 =52÷13+26/17÷13 =4+2/17...

(1)(214) 12-9.60-(338) 23+1.5-2 =32?1?94+94=12.(2...

=9.16*(1.53-0.53) =9.16*1 =9.16 请采纳!

9.16x1.53-o.o53x91.6 =91.6×0.153-0.053×91.6 =91.6×...
