Step 1
- Pad to a multiple of 4 bits: 1011001 -> 01011001. - Split into nibbles: 0101 1001. - Convert each nibble: 0101 = 5, 1001 = 9. - Result: (1011001)BCD = (59)10. Show more…

1.14 Obtain the 1's and 2's complements of the following binary numbers: (a) 11100010 (b) 00011000 (c) 10111101 (d) 10100101 (e) 11000011 (f) 01011000. 1.15 Find the 9's and the 10's complement of the following decimal numbers: (a) 65,234,035 (b) 56,783,223 (c) 87,000,367 (d) 99,999,000. 1.16 (a) Find the 8's complement of (2360)s. (b) Convert (2360)s to binary. 1.17 Perform subtraction on the given unsigned numbers using the 10's complement of the subtrahend. Where the result should be negative, find its 10's complement and affix a minus sign. Verify your answers. (a) 7,523 - 4,567 (b) 230 - 1,204 (c) 224 - 712 (d) 2,390 - 945 1.18 Perform subtraction on the given unsigned binary numbers using the 2's complement of the subtrahend. Where the result should be negative, find its 2's complement and affix a minus sign. (a) 11001 - 10010 (b) 1100 - 11100 (c) 10101 - 11011 (d) 1100011 - 10001 1.19 The following decimal numbers are shown in sign-magnitude form: +9,286 and +801. Convert them to signed-10s-complement form and perform the following operations (note that the sum is +10,627 and requires five digits and a sign). (a) (+9,286) + (+801) (b) (+9,286) + (-801) (c) (-9,286) + (+801) (d) (-9,286) + (-801) 1.22 Convert decimal 9,045 and 337 to both BCD and ASCII codes. For ASCII, an even parity bit is to be appended at the left. 1.23 Represent the unsigned decimal numbers 609 and 516 in BCD, and then show the steps necessary to form their sum.
