1.25×7.1＋0.125×2.6+0.375,简便算法1.25×7.1＋0.125×2.6+0.375,简便算法1.25×7.1＋0.125×2.6+0.375,简便算法=0.125*10*7.1
1.25×7.1＋0.125×2.6+0.375,简便算法
1.25×7.1＋0.125×2.6+0.375,简便算法
1.25×7.1＋0.125×2.6+0.375,简便算法
=0.125*10*7.1+.125*2.6+.125*3
=.125*(71+2.6+3)
=.1/8*76.6
=9.575
0.125*71+0.125*2.6+0.125*3=1/8*(71+3)+1/8*(2+0.6)=1/8*(80-6)+1/8*(2+0.6)
=10-6/8+2/8+0.6/8=10-3.4/8=10-0.425=9.575

7.1÷1.25简算
32.5×1.25＋715×0.125＋215÷8－2.55×12.5
1.25×9.1×7.1+1.25×9.1×0.1
-3.75+2.6+(-1.25)+(-5.6)
(1.25—0.125)x8
1.25×99＋1.25
1.25%*2.6+5.4*1.25%用简便计算
x-2.6+1.25=3.75
