0.25x1.38x4用脱式计算该怎么算?

计算步骤: =34.8乘以(0.25乘以4) =34.8乘以1 =34.8

800÷25 =(800x4)÷(25x4) =3200÷100 =32

250x17x4 =250x4x17 =1000x17 =17000

168÷4+20×4 =42+80 =112

75x4x25x4 =(75x4)x(25x4) =300x100 =30000

0.75×4+0.75×4=6 ~回答完毕~ ~\(^o^)/~祝学习进步~~~

2.5x45x0.4 =2.5x0.4x45 =1x45 =45

3.6x0.25 =0.9x4x0.25 =0.9x(4x0.25) =0.9x1 =0.9

5.73x4.27+5.73x5.73 =5.73x(4.27+5.73) =5.73x10 =57.3
