Denary to Binary

Question 1

Denary to Binary

Answer 1

You are given a binary number with a maximum of 8 bits. Like before, you should write 128 to 1 on the top of the page. Next, write the binary number underneath in its corresponding column. After this, starting at 128, note down which column has a 1 and a 0. If the number has a 1 then add it. If the number has a 0 then ignore it. This will give you the denary number at the end.
