Write each of the following rational numbers in the standard form: (i) 4/(-16) (ii) (-15)/(-35)

If A= {1, 2, 3}, B= {3, 4} and C= {4, 5, 6}, then (A xx B) uu (A xx C) = {(1, 3), (1,4), (1,5), (1,6), (2,3), (2,4), (2,5), (2,6), (3,3), (3,4), (3,5),(3,6)}

If in triangle A B C ,sumsin(A/2)=6/5a n dsumI I_1=9 (where I_1,I_2 a n d I_3 are excenters and I is incenter, then circumradius R is equal to (15)/8 (b) (15)/4 (c) (15)/2 (d) 4/(12)
