3.68 4.6 6.32简便计算

3.68/4.6+6.32 把3.68/4.6同时除以2.3化简成1.6/2 那么3.68除以4.6加上6.32=0.8+6.32=7.12

3.68/4.6+6.32=0.8+6.32=7.12

0.56乘以3.68+6.32等于5.6

(1)6.32+7.89+3.68=6.32+3.68+7.89=10+7.89=17.89;(2)25.23-7.85-2.15=25.23-(7.85+2.15)=25.23-10=15.23;(3)125*(73*8)=125*8*73=1000*73=73000;(4)302*99+302=302*(99+1)=302*100=30200;(5)7200÷4÷25=7200÷(4*25)=7200÷100=72;(6)462*58÷231=462÷231*58=2*58=116.

23.2-3.68-6.32=23.2-(3.68+6.32)=23.2-10=13.2

解:0.56X(3.68+6.32)=0.56X10=5.6

3.68÷4.6+6.32=0.8+6.32=7.121.8X(4.7-3.87÷0.9)=1.8X(4.7-4.3)=1.8X0.4=0.72

21.73一6.32十5.27一3.68=(21.73+5.27)-(6.32+3.68)=27-10=17

2.8*4.6-3.68=2.8*4.6-4.6*0.8=2.8-0.8*4.6=2*4.6=9.2

20.7-6.32-36.8乘0.1 =20.7-6.32-3.68 =20.7-(6.32+3.68) =20.7-10 =10.7
