解:7/12-(3/8+1/6)等于( 1/24 )      
∵已知需求出7/12-(3/8+1/6)等于多少      
∴7/12 - (3/8 + 1/6)      
= 7/12 - 3/8 - 1/6      
= (7×4)/(12×4) - (3×6)/(8×6)-(1×8)/(6×8)     
= 28/48 - 18/48 - 8/48     
= 10/48 - 8/48     
= 2/48      
= 1/24       
答:7/12-(3/8+1/6)等于1/24

7/12-(3/8+1/6)
=7/12-3/8-1/6
=7/12-2/12-3/8
=5/12-3/8
=10/24-9/24
=1/24
