The Binary number for the base 10 number 15 is 1111 Think about it: you should first set up the first four place values, which are - - - - 8 4 2 1 First, divide 15 (or the number your working with) by the largest place value (not bigger than the number you're dividing by) which, in this case, is 8. 15/8 is 1 R 7, so put 1 in the 8 place value spot. Since you have 7 remaining, put another 1 in the 4's place, than another 1 in the 2's place, and another in the 1's place. You have nothing left to divide, so this is your answer. 15 (base 10) = 1111 (base 2, or Binary)
