Question

Convert following hexadecimal numbers into binary number :
(a) FF
(b) ABC
(c) CD42
(d) F329

Answer 1

Answer:

(a) 1111 1111

(b) 1010 1011 1100

(c) 1100 1101 0100 0010

(d) 1111 0011 0010 1001

Explanation:

In this question

We can find the binary number of FF

In hexadecimal number F = 15

so, binary number of 15 = 1111

Therefore, the binary number of FF is 1111 1111

similarly, we can find the binary number of ABC

In hexadecimal number A = 10, B = 11, C = 12

so, binary number of 10 = 1010

     binary number of 11 = 1011

     binary number of 12 = 1100

Therefore, the binary number of ABC is 1010 1011 1100

similarly, we can find the binary number of CD42

In hexadecimal number C = 12, D = 113

so, binary number of 12 = 1100

     binary number of 13 = 1101

     binary number of 4 = 0100

     binary number of 2 = 0010

Therefore, the binary number of CD42 is 1100 1101 0100 0010

similarly, we can find the binary number of F329

In hexadecimal number F = 15

so, binary number of 15 = 1111

     binary number of 3 = 0011

     binary number of 2 = 0010

     binary number of 9 = 1001

Therefore, the binary number of F329 is 1111 0011 0010 1001
