2.4x3 0.8的脱式计算

2.4x3÷0.18=7.2÷0.18=40

24x3÷018=72÷018=40

你好!2.4x0.8÷0.24=2.4÷0.24*0.8=10*0.8=8 仅代表个人观点,不喜勿喷,谢谢.

1、直接写出得数.0.45*2.5=1.1250.8*1.25=10.3*3.6=1.080.3*0.3=0.0910*0.07=0.70.92*0.4=0.3680.2*0.26=0.0520.14*4=0.560.02*0.1=0.0021.2*0.3=0.362.5*0.4=12.4*5=120.22*4=0.883.25*0=00.9-0.52=0.383.99*1=3.990*3.52=012.5*8=

2.4 x 2.5 + 1.6 x 2.5= 2.5 x (2.4 + 1.6)= 2.5 x 4.0= 10.02.4 x 2.5 - 1.6 x 2.5= 2.5 x (2.4 - 1.6)= 2.5 x 0.8= 2.0

2.4*7.8÷3.6=7.8x(2.4/3.6)=7.8x2/3=5.2如有帮助请采纳,如对本题有疑问可追问,Good luck!

解: 4.3-(0.6-2.4÷0.8)=4.3-0.6+3=3.7+3=6.7

96.72÷2.4X1.5=96.72X0.5X3÷(3X0.8)=48.36÷0.8=60.45

30.8÷[14-(9.85+1.07)] [60-(9.5+28.9)]÷0.18 2.881÷0.43-0.24*3.5 20*[(2.44-1.8)÷0.4+0.15] 28-(3.4 1.25*2.4) 2.55*7.1 2.45*7.1 777*9 1111*3 0.8*〔15.5-(3.21 5.79)〕 (31.8

(1000-195)\(3.4+0.8) 脱式计算有过程解,得:==(1000-195)/(21/5)==(1000-195)*(5/21)==1000*(5/21)-195*(5/21)==5000/21-975/21==(5000-975)/21==4025/21==575/3
