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乘(2.5除2.4)乘4.8+0.8乘5 = (1.2乘2.5)乘(4.8除2.4)+0.8乘5 = 3乘2 + 4 = 6 + 4 = 10

=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.

(3.4乘以4.8乘以9.5)除以(1.9乘以1.7乘以2.4)= (3.4/1.7)*(4.8/2.4)*(9.5/1.9)=2*2*5=20

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

4/15X(5/10十7/10)二4/15x12/10二24/75

42÷0.048×8.1×4.8÷0.81 是这个式子吗

用简便计算 7.5÷(3.7-1.2)×0.8 =7.5÷2.5×0.8 =3×0.8 =2.4
