Question

怎样简便就怎样算．
5.75-0.76-24%
（(7)/(8)-(5)/(6)+(1)/(3)）×24
9.36×3.4+6.4×0.34
96÷[25-（80-58）]．

Answer 1

（1）5.75-0.76-24%
=5.75-（0.76+0.24）
=5.75-1
=4.75

（2）（(7)/(8)-(5)/(6)+(1)/(3)）×24
=(7)/(8)×24-(5)/(6)×24+(1)/(3)×24
=21-20+8
=1+8
=9

（3）9.36×3.4+6.4×0.34
=93.6×0.34+6.4×0.34
=（93.6+6.4）×0.34
=100×0.34
=34

（4）96÷[25-（80-58）]
=96÷[25-22]
=96÷3
=32
