How do you write 68 in binary notation?
You can do this with the following technique:divide the number by two, rounding down.write down the remainder.repeat those two steps until your number is equal to 0Now read those remainders backwards. That will be the binary notation of your number.For example, to convert the number "123":123 / 2 = 61 R 161 / 2 = 30 R 130 / 2 = 15 R 015 / 2 = 7 R 17 / 2 = 3 R 13 / 2 = 1 R 11 / 2 = 0 R 1So "123" in decimal is equal to 1111011 in binary. In the case of the number 68, it would be like so:68 / 2 = 34 R 034 / 2 = 17 R 017 / 2 = 8 R 18 / 2 = 4 R 04 / 2 = 2 R 02 / 2 = 1 R 01 / 2 = 0 R 1
