简便方法1: 6.27x3.6+37.8x0.36 2: 369x0.99+3.69 3: 13.5...

1. 6.27*3.6+37.8*0.36 =6.27*3.6+3.78*3.6 =(6.27+3.78)*3.6 =10.05*3.6 =36.182: 369*0.99+3.69 =3.69*99+3.69 =3.69*(99+1) =3.69*100 =369 3: 13.5*2.5-0.35*25 =13.5*2.5-3.5*2.5 =(13.5-3.5)*2.5 =10*2.5 =25

1. 6.27*3.6+37.8*0.36=6.27*3.6+3.78*3.6=(6.27+3.78)*3.6=10*3.6=362. 369*0.99+3.69=3.69*99+3.69=3.69*(99+1)=3.69*100=3693. (0.64+0.32)÷0.64=(0.32*2+0.32)÷0.64=(2+1)*0.32

6.27*3.6+37.8*0.36 369*0.99+3.69 (0.64+0.32)÷0.64 13.5*2.5-0.35*256.27*3.6+37.8*0.36=6.27*3.6+3.78*3.6=3.6*(6.27+3.78)=3.6*(10+0.05)=36+0.18=36.18369*0.99+3.69 =369*0.99+369*0.01=369*(0.99+0.01)=369*1=369(0.64+0.32)÷0.64 =0.64/0.64+0.32/0.64=1+1/2=1.513.5*2.5-0.35*25=1.35*25-0.35*25=(1.35-0.35)*25=25

6.27*3.6+37.8*0.36=6.27*3.6+3.78*3.6=3.6*(6.27+3.78)=3.6*10=36

(1)=(6.27+3.78)*3.6 =10.05*3.6(你是不是打错数字了?) =36.18(2)=0.64/0.64+0.32/0.64 =1+0.5 =1.5(3)=3.69*99+3.69 =(99+1)*3.69 =369

6.27X3.6+37.8X0.36=6.27x3.6+3.78x3.6=36369X0.99+3.69=369x(0.99+0.01)=369(0.64+0.32)/0.64=1+0.32/0.64=3/213.5X2.5-0.35X25 =1.35x25-0.35x25=1x25=25选我!拜托了!

6.27乘3.6加37.8乘0.36=6.27*3.6+3.78*3.6=(6.27+3.78)*3.6=10.05*3.6=10*3.6 +0.05*3.6=36+0.18=36.18 没戏唱了,又被他舅抢了先.分数就不想了.楼主新春快乐!

(6.27+3.78)*3.6=36.18

因为3.69=369*0.01所以原始等于369*0.99+369*0.01=369*1

6.72*3.6+37.8*0.36=67.2*0.36+37.8*0.36=(67.2+37.8)*0.36=105*0.36=37.8369*0.99+3.69=3.69*99+3.69=3.69*(99+1)=3.69*100=369(0.64+0.32)/0.64 =(0.64+0.32)*(1/0.64)=0.64*(1/0.64)+0.32/(1/0.64)=1+1/2=3/213.5*2.5-0.35*25 =1.35*25-0.35*25=(1.35-0.35)*25=1*25=25
