67.5÷0.125+32.5×8
75.43÷0.01-25.43×100
6.3-(2.1÷1.15)

几道弱智五年级简便计算67.5÷0.125+32.5×875.43÷0.01-25.43×1006.3-(2.1÷1.15)
67.5÷0.125+32.5×8
=67.5*8+32.5*8
=(67.5+32.5)*8
=100*8
=800
75.43÷0.01-25.43×100
=75.43*100-25.43*100
=(75.43-25.43)*100
=5000
6.3-(2.1÷1.15)
=6.3-2
=4.3

67.5÷0.125+32.5×8 =67.5÷(1/8)+32.5×8=67.5×8+32.5×8=8(67.5+32.5)=800
