Step-by-step explanation:

a) -9/11+2/3+(-5)/4 = -9/11+2/3-5/4 = 2/3-(9/11+5/4) =2/3-36+55/44 =2/3-91/44           =88-273/132 = -85/132 (ans)          b)3/8+(-11/16)-(-11/24) = 3/8-11/16+11/24              =(3/8+11/16)-11/16 = 9+11/24-11/16 = 20/24-11/16 = 40-33/48 = 7/48 (ans)       c) 1/6          +(-2/5)-(-2/15) = 1/6+2/15-2/5=5+4/30-2/5=9-12/30= -3/30= -1/10 (ans)  d) 56/7//-8/14 =56/7*14/-8= -16 (ans)  e)(-16/5*15/8)-15/20*-35/3= -6-(-35/4) = -6+35/4 =35/4-6 = 35-24/4 = 11/4 (ans) f) (13/15-3/5) //(13/15-3/5)= 13-9/15//13-9/15=4/15//4/15=4/15*15/4=1*1=1 (ans) g) -6/14//6/14= -6/14*14/6= -1(ans)
