1) Since this is a positive number. we can directly convert this into binary Divide 15 successively by 2 until the quotient is 0 > 15/2 = 7, remainder is 1 > 7/2 = 3, remainder is 1 > 3/2 = 1, remainder is 1 > 1/2 = 0, remainder is 1 Read remainders from the bottom to top as 1111 So, 15 of decimal is 1111 in binary Adding 4 zeros on left hand side of this number to make this of length 8 so, 15 in 2's complement binary is 00001111 Answer: 00001111 2) This is negative. so, follow these steps to convert this into a 2's complement binary Step 1: Divide 75 successively by 2 until the quotient is 0 > 75/2 = 37, remainder is 1 > 37/2 = 18, remainder is 1 > 18/2 = 9, remainder is 0 > 9/2 = 4, remainder is 1 > 4/2 = 2, remainder is 0 > 2/2 = 1, remainder is 0 > 1/2 = 0, remainder is 1 Read remainders from the bottom to top as 1001011 So, 75 of decimal is 1001011 in binary Adding 1 zeros on left hand side of this number to make this of length 8 So, 75 in normal binary is 01001011 Step 2: flip all the bits. Flip all 0's to 1 and all 1's to 0. 01001011 is flipped to 10110100 Step 3:. Add 1 to above result 10110100 + 1 = 10110101 so, -75 in 2's complement binary is 10110101 Answer: 10110101 3) This is negative. so, follow these steps to convert this into a 2's complement binary Step 1: Divide 3 successively by 2 until the quotient is 0 > 3/2 = 1, remainder is 1 > 1/2 = 0, remainder is 1 Read remainders from the bottom to top as 11 So, 3 of decimal is 11 in binary Adding 6 zeros on left hand side of this number to make this of length 8 So, 3 in normal binary is 00000011 Step 2: flip all the bits. Flip all 0's to 1 and all 1's to 0. 00000011 is flipped to 11111100 Step 3:. Add 1 to above result 11111100 + 1 = 11111101 so, -3 in 2's complement binary is 11111101 Answer: 11111101 4) Since this is a positive number. we can directly convert this into binary Divide 109 successively by 2 until the quotient is 0 > 109/2 = 54, remainder is 1 > 54/2 = 27, remainder is 0 > 27/2 = 13, remainder is 1 > 13/2 = 6, remainder is 1 > 6/2 = 3, remainder is 0 > 3/2 = 1, remainder is 1 > 1/2 = 0, remainder is 1 Read remainders from the bottom to top as 1101101 So, 109 of decimal is 1101101 in binary Adding 1 zeros on left hand side of this number to make this of length 8 so, 109 in 2's complement binary is 01101101 Answer: 01101101
