24.3除以4.5加3.2乘以0.8怎样简便就怎样算

24.3除以4.5加3.2乘以0.8怎样简便就怎样算 24.3除以4.5加3.2乘以0.8 =5.4+2.56 =7.96 直接计算

24.3除以4.5加3.2乘以0.8怎样简便就怎样算 24.3除以4.5加3.2乘以0.8 =5.4+2.56 =7.96 直接计算

24÷3/8 =24×8/3 =64

3.24÷1.5÷0.8 =3.24÷0.3÷5÷0.8 =10.8÷0.8÷5 =13.5÷5 =2.7

第一个用(0.5×0.8 )×0.24

解:原式=39.16.

0.24× 0.8× l.3 =0.24× 0.8×(1+0.3) =0.24×( 0.8×1+0.8×0.3) =0.24×(0.8+0.24) =0.24×1.04 =0.24×(1+0.04) =0.24+0.24×0.04 =0.24+0.0096 =0.2496

递等式

8.7 +( 1.2 x 0.35)= 8.7 + 0.42 = 9.12 0.24 x 0.8 x 1.3 = 0.2496 请采纳答案,支持我一下。

300÷125÷8=300÷(125×8)=300÷1000=0.3 396-96-172-28 =(396-96)-(172+28)= 300-200 = 100 125*24 = 125*8*3 = 1000*3 = 3000 26*15 = (20+6)*15 = 20*15 + 6*15 = 300+90 =390 25*99*4 = 25*4*99 = 100*99 = 9900 250*32 = 250*4*8 = 100...
