Answer 1

1, 120 in binary: - * 120 divided by 2 and reverse the numbers. 120 rightarrow 1111000 hexa decimal: - 120 rightarrow 0001 0010 0000 * In this every number write in 4, bits. 2, E5H In decimal: - E5 rightarrow 1111 1001 * hexa number converted into binary. after that we converted into decimal. 1111 1001 2^7 times 1 + 2^6 times 1 2^5 times 1 + 2^4 times 1 + 2^3 times 1 + 2^2 times 0 + 2^1 times 0 + 2^0 times 1 = 128 + 64 + 32 + 16 + 8 + 1 = 249 E5H rightarrow 249 - In decimal E5H rightarrow 1111 1001 rightarrow In binary \r\n 3. 0111 1011 In decimal: - 0111 1011 2^7 times 0 + 2^6 times 1 + 2^5 times 1 + 2^4 times 1 + 2^3 times 1 + 2^2 times 0 + 2^1 times 1 + 2^0 times 1 = 0 + 64 + 32 + 16 + 8 + 0 + 2 + 1
