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%4.5+3.2x0.8怎么简算 24.3%4.5+3.2x0.8 =24.3÷4.5+3.2*0.8 =5.4+2.56 =7.96

表示24是3的8倍 或者表示24里有8个3

3.6x5.7+3.67 =20.52+3.67 =24.19 2.57x99+2.57 =2.57x(99+1) =2.57x100 =257 5.3-0.6x0.24 =5.3-0.144 =5.156 3.9x4.5+4.5x6.1 =(3.9+6.1)x4.5 =10x4.5 =45 1.25x27x0.8 =1.25x0.8x27 =1x27 =27 2.5x(40+4+0.4) =2.5x4x11.1 =10x11.1 =111

24.32除以1.6除以0.8 =15.2/0.8 =19 2.6乘以16乘以0.4 =41.6X0.4 =16.64 15.99除以3.加18.9 =5.33+18.9 =24.23

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

对 但是注意 a÷(b+c)不等于a÷b+a÷c 仅供参考

300÷125÷8=300÷(125×8)=300÷1000=0.3396-96-172-28=(396-96)-(172+28)=300-200=100125*24=125*8*3=1000*3=300026*15=(20+6)*15=20*15+6*15=300+90=39025*99*4=25*4*99=100*99=9900250*32=250*4*8=1000*8=8000(98+98+98+98)*25=4*98*25...

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