Can somebody help me with this question float binary arithmetic question?

You should provide answer with step by step with format that model answer used. Check model answer form down below. The question that I'm asking for is Question 4 not Question 2 which is model answer question.

+ In adition, can you explain to me how 1 001 0010 becomes hex number of 92?

Question 4 Contents of the byte-addressable memory with symbolic addresses are shown below. The contents are represented in hexadecimal. Each byte is a floating-point number. The format of the floating-point number is: 1 sign bit, 3-bit biased exponent. Address A B D A5 36 48 Show all the steps in performing the following floating-point arithmetic. D= A x (B+C) Show the content in memory location D in hexadecimal. Question 2 The byte-addressable memory with symbolic addresses is shown below. The contents are represented in hexadecimal. Show all the steps in performing the floating-point arithmetic D= (A -B)x C The format of the floating-point number is: 1 sign bit, 3-bit biased exponent.
