help me solve this

2. Converting the following decimal numbers to 8-bit floating point number format. Specially, among the 8 bits, the first bit store the sign bit, the next 3 bits store the biased exponent, and the remaining 4 bits store the significand. Requirements: show your transformation step by step. Specifically, you need to show how you transformed the number to binary form and then the normalized form: +1.bbbb x 2. Then, write the biased exponent, and finally the 8-bit representation Note: the bias used for the exponent is 2k-1 - 1, where k is the number of bits to represent the biased exponent. Positive number is represented by bit 0 Decimal numbers: (1) 3.625; (2) 0.375 (3) 1.9 (4) -2.75 (2.5 pts for each case)
