please answer question number 7

7. The following 6-bit two's complement integers were found in a computer. What decimal number do they represent? a 000101 *c. 010101 101010 b. 111111 *d. 100100 f. 111001 *h. 100000 e. 011111 c. 9. Each of the following pairs of signed (two's complement) integers are stored in computer words (6 bits). Compute the sum as it is stored in a 6-bit computer word. Show the decimal equivalents of each operand and the sum. Indicate if there is overflow. *a. 110101 001100 e. 011010 001111 110100 001100 b. 111010 *d. 101010 *f. 111101 000111 100110 110000 10. For each of the following pairs of integers, subtract the second from the first. Show the operands and the answers in decimal, assuming i. the numbers are unsigned ii. the numbers are signed (two's complement). Indicate overflow where appropriate. a. 010101 *c. 111010 e. 110010 001100 000111 110111 *b. 010001 *d. 100100 f. 111010 011000 011000 101101
