Convert 'A1' hexadecimal value into binary.
Firstly split the number into 2 since there are two numbers. A and 1. We first convert 'A' into decimal. The corresponding value is 10. We then convert 10 into binary which is 1010. That is the first part of the conversion. then we deal with '1'. The decimal value is 1 and the binary value is 0001. That is the second part of the conversion. We put the two parts together to get 10101000 binary which is A1 in hexadecimal.
