I have been studying for the CCNA test. I have been using the Trainsignal DVD which is very thorough. But when I tried some parctice tests at the Cisco website I got a couple of binary conversion questions that I did not understand. Can someone explain the meaning of these two questions.

- The decimal number 452 converted into a binary number, using successive division by 2, is _____.

- The binary number 11101000111 converted into a decimal number, using powers of 2, is _____.

Thanks
