You can use any of the methods given below. Decimal number system has a base of 10 while the binary number system has a base of 2 which means that only 2 symbols are available for notation which is ‘0’ and ‘1.’

1. By the trivial method, you can simply convert an n-bit unsigned integer to n-1 bit signed integer where the MSB denote the sign of the integer. 0 is used to denote positive and 1 is used to denote negative.
2. You can also convert a given number to its 1’s complement form to obtain the equivalent negative number.
