Answer:
-B9C
Step-by-step explanation:
Hi!
Firstly,
1) Start dividing -2972 : 16 = -185 (quotient) *(16) -12 Remainder
2) Do it again! Divide -185 for 16 = -185 / 16 = -11 (quotient) *(16) - 9 Remainder
3) Divide = -11/16 there's no integer result (since it's 0.68) we put it 0*16 -11 (Remainder) = 11
(Since the result gave us a 0 as integer. We had to lower it one unit the Remainder to satisfy the division algorithm which says = a:b=q*b +r,
11 =0*16+11
4) Gathering all Remainders from bottom to top: 12912
Comparing with the Table (below), from the last remainder to the first, and checking it with the table:
Decimal = Hex (multiplying by minus 1 since it's negative):
-11912 =-B9C
