1.2乘(2.5除2.4)乘4.8简便计算

1.2×(2.5÷2.4)×4.8 =1.2×2.5÷2.4×4.8 =1.2×2.5×(4.8÷2.4) =1.2×2.5×2 =1.2×(2.5×2) =1.2×5 =6

=1.2/2.4x9.6/4.8 =1/2x2 =1 请采纳!

1.2X(9.6除2.4)除4.8 简便计算 1.2×(9.6/2.4)÷4.8 =(1.2×9.6)/(2.4×4.8) =2.4/2.4 =1.

1.2乘5.2减2.5除0.3简便计算 1.2乘5.2减2.5除0.3 =1.2*5.2-2.5÷0.3 =6.24- 2.5÷0.3 结果不是有限小数 核实算式

(4.8×7.5×8.1)÷(2.4×2.5×2.7) =(4.8÷2.4)x(7.5÷2.5)x(8.1÷2.7) =2x3x3 =18

1.2*2.5+0.08*25 =1.2*2.5+0.8*2.5(一个因数扩大多少倍另一个因数缩小相同的倍数积不变) =(1.2+0.8)*2.5 =2*2.5 =5

1.2÷2.4+3.6÷2.4 =(1.2+3.6)÷2.4 =4.8÷2.4 =2

4÷(2.1-2.05)x2.5 =4x2.5÷0.05 =10÷0.05 =10/0.05 =1000/5 =200 谢谢,请采纳

(1又2/3+5/21-9/14)乘42 =5/3*42+5/21*42-9/14*42 =5*14+5*2-9*3 =70+10-27 =53
