8分之9×中括号4分之3-括号16分之7减8分之1除2分之一括号

Answer 1

8分之9×中括号4分之3-括号16分之7减8分之1除2分之一括号
=9/8X[3/4-(7/16-1/2÷1/8)]
=9/8X[3/4-(7/16-1/2X8)]
=9/8X[3/4-(7/16-4)]
=9/8X[3/4-(7/16-64/16)]
=9/8X[3/4-(-57/16)]
=9/8X[3/4+57/16]
=9/8X[12/16+57/16]
=9/8X[69/16]
=621/128
8分之9×中括号4分之3-括号16分之7减8分之1除以2分之一括号
=9/8X[3/4-(7/16-1/8÷1/2)]
=9/8X[3/4-(7/16-1/8X2)]
=9/8X[3/4-(7/16-1/4)]
=9/8X[3/4-(7/16-4/16)]
=9/8X[3/4-(3/16)]
=9/8X[12/16-3/16]
=9/8X[9/16]
=81/128

Answer 3

9/8*(3/4-(7/16-1/8/1/2))=0.42

Answer 4

题目不清楚，再打一次，括号标清楚
