помогите пожалуйста решить выражение:
(1/6+0.1+1/15):(1/6+0.1-1/15)*2.52
________________________________
(0.5_1/3+0.25-1/5):(0,25-1/6)*7/13
1)(5/30+3/30+2/30):(5/30+3/30-2/30)*2.52=(10/30)*(30/6)*2.52=(10/6)*(252/100)=
=252/6=42
2)(150/300-100/300+75/300-60/300):(75/300-50/300)*7/13=(115/300)*(300/25)*7/13=
=(23/5)*(7/13)=161/65
