Answer 2

You are converting from base 2 to base 10 numeral.


`(011001111)_2 =0 * {2}^(8) + 1 * {2}^(7) + 1* {2}^(6) + 0* {2}^(5) + 0 * {2}^(4) + 1 * {2}^(3) + 1 * {2}^(2) + 1 * {2}^(1) + 1 * {2}^(0)`



`(011001111)_2 =0 * 256 + 1 * 128 + 1* 64 + 0* 32 + 0 * 16 + 1 * 8 + 1 * 4 + 1 * 2 + 1 * 1`


`(011001111)_2 =0 + 128 +64 + 0+ 0 + 8 + 4 + 2 + 1`

`(011001111)_2 =207`
