Convert 20ten to a binary. Explain your answer

Answer 1

In binary, 20ten is written as 10100.

To convert 20ten to binary, we divide 20 by 2 repeatedly and record the remainders.

20 ÷ 2 = 10 with remainder 0
10 ÷ 2 = 5 with remainder 0
5 ÷ 2 = 2 with remainder 1
2 ÷ 2 = 1 with remainder 0
1 ÷ 2 = 0 with remainder 1

Reading the remainders from bottom to top, we get 10100, which is the binary equivalent of 20ten.
