Converting Binary and Decimal Numbers

When converting the binary number 110010101 to decimal you first must list the number with powers above from right to left. Then start with 2 to the power of 0, and go up one per power. Stop when you have reached the same amount in binary numbers. For every binary number one that you have, write the power that above it. Write each power out and add them together and you should get 405 as your answer.

When converting the decimal number 529 to binary, you simply divide by 2. When dividing the number 529 if it divides evenly by 2, mark it as a 0 and if it does not divide evenly put a 1 next to that number. Each time you divide the number should go down by half, when it does this just mark down a 1 or a 0 if pending if it divided evenly or not. When you are complete with these steps it should leave you with the binary number.
