Answer:
11.125
Explanation:
The binary numeral system uses the number 2 as its base (radix). As a base-2 numeral system, it consists of only two numbers which are 0 and 1. In order to convert binary to decimal, basic knowledge on how to read a binary number might help. As I cannot share links over Brainly I won't be able to give resources, but usually a simple search will bring up videos / websites that will help!
Hopefully this is correct, have a nice day! :D
