簡算:96又5/8-99.32+3又3/8-68%
96又5/8-99.32+3又3/8-68%
3.87×2/3-0.87÷1.5+2/3
[100×(9.05+0.905)]×(2.5×0.4-1)

解答:

96又5/8-99.32+3又3/8-68%
=96+3+5/8+3/8-99.32-0.68
=99+1-(99.32+0.68)
=100-100
=0
3.87×2/3-0.87÷1.5+2/3
=3.87*2/3-0.87*2/3-2/3
=(3.87-0.87+1)*2/3
=4/2/3
=8/3
[100×(9.05+0.905)]×(2.5×0.4-1)
=【100*(9.05+0.905)】*0
=0
