32.8 5.6 7.2怎么简算

32.8x5.6的简便运算32.8x5.6=183.68直接计算没有简算

32.8+5.6-2.8解:简便计算32.8+5.6-2.8=32.8-2.8+5.6 =30+5.6=35.6祝天天向上.

(5.6+8)*7.2的简算方法(5.6+8)*7.2=12.6*7.2=90.72直接计算

32.8*(5.6-4.8)=32.8x0.8=26.24互相帮助

32.8*0.2+7.2/5=32.8/5+7.2/5=(32.8+7.2)/5=40/5=8

7*32.8+4.5*28 =7*(32.8+18)=7*(50+0.8)=35+5.6=40.6 3.75-1.75*0.24 =0.25*(15-1.68)=1/4*13.32= 3.33 4.8*9.9 =4.8*(10-0.1)=48-0.48=47.52 0.2*5.37*50=5.37*(0.2*50)=5.37*10=53.7 2.5*3.2*0.125 =(2.5*0.4)*(8*0.125) =1 12.5*(80+0.8) =1000+10=1010 0.76*4.92+5.08*0.76=0.76*(4.92+5.08)=0.76*10=7.6

(32.8-X)x2.8=5.632.8-X=2X=30.8

列竖计算4.8x6.3、32.8x5.64.8*6.3=48*63÷100=3024÷100=30.24,32.8*5.6=328*56÷100=18368÷100=183.68.

32.8+5.6-2.8 =(32.8-2.8)+5.6=35.6 5.7*3.8+6.2*5.7 =5.7*(3.8+6.2)=57 91/0.25+9*4 =4*(91+9)=40 7.2/【6*(3.24-3.04)】 =1.2/0.2=6 4.2/0.35/2 =4.2/(0.35*2)=6 88.8*0.9-33.3*1.4=11.1*(7.2-4.2)=11.1*3=33.3

*是乘号 /是除号 0.3*2.5*0.4 50*0.13*0.2 0.8*630*0.125 0.78*101 1.5*102 9.8*25 1.2*2.5+0.8*2.5 1.25*0.7*0.8 0.038*5*2.1 3.8+4.5+6.2 93/0.31/3 3.25-0.84-0.16 88*0.25*4 2.8*3.6+1.4*2.8 63*10.1 (3.2+0.128)/0.8 9.83*1.5+6.17*1.5 10.1*87 312*4
