Convert A = (10.5)₁₀ and B = (2.40)₁₆ to binary using 7 bits for the integer part and 2 bits for the fractional part including the bit of the sign. Perform the following binary arithmetic operations using the signed supplement indicated for each operation:

i) C = A - B with complement to 1

ii) D = -A + B with complement to 2

iii) E = A - B with complement to 9
