-1-[3/5-(-2-1/3)+1/15]= ​

Answer 1

-2/9-(2/3-(-9/12+2/12))+17/36
-2/9-(2/3-(-7/12))+17/36
-2/9-(2/3+7/12)+17/36
-2/9-(8/12+7/12)+17/36
-2/9-15/12+17/36
-8/36-45/12+17/36
-53/36+17/36
-36/36
-1

-2/9-2/7+(2/3+3/4)+23/252
-2/9-2/7+(8/12+9/12)+23/252
-2/9-2/7+17/12+23/252
-56/252-72/252+357/252+23/252
-128/252+357/252+23/252
229/252+23/252
252/252
