追答

1/3÷[(2/3＋1/5)×1/13]
=1/3÷[(10/15+3/15)×1/13]
=1/3÷[13/15×1/13]
=1/3÷1/15
=1/3×15
=5
[17/12-(3/4-1/6)]÷10/3
=[17/12-(9/12-2/12)]×3/10
=[17/12-7/12]×3/10
=10/12×3/10
=1/4

Answer 2

1/3÷[(2/3＋1/5)×1/13] [17/12-(3/4-1/6)]÷10/3
=1/3÷10/3÷1/13÷[(2/3＋1/5)] [17/12-(3/4-1/6)]
=13/10÷13/15x[17/12-7/12]
=3/2x5/6
=5/4
