1/2-(-7/6)=1/2+7/6=(3+7)/6= 10/6=2/3
1+1/2 -11/12=(12+6-11)/12= 7/12
3/5+7/3.2/5= 3/5+14/15=(9+14)/15= 23/15
3/7.(5/4+3/7) -1= (15/28+9/49)-1= [15(49)+28(9)]/1372-1=[375+252]/1372-1
=627/1352-1
=-725/1352
(3/8)/5/3 - 3/2= 9/40-3/2= (9-60)/40= -51/40
(1/2-3/7).(15/4+3/2)-1= (7-6)/7.(15+6)/4-1=5/7.21/4-1=105/28-1=77/28
1+1/2 -11/12=(12+6-11)/12= 7/12
3/5+7/3.2/5= 3/5+14/15=(9+14)/15= 23/15
3/7.(5/4+3/7) -1= (15/28+9/49)-1= [15(49)+28(9)]/1372-1=[375+252]/1372-1
=627/1352-1
=-725/1352
(3/8)/5/3 - 3/2= 9/40-3/2= (9-60)/40= -51/40
(1/2-3/7).(15/4+3/2)-1= (7-6)/7.(15+6)/4-1=5/7.21/4-1=105/28-1=77/28
