I have a Computing 1 test on Tuesday

I would like help with the past paper I am working on this question

The IEEE-754 standard for 32-bit Single-Precision Floating-point number representation is the

industry standard for representing real numbers in modern computer systems, where the 32-bits

are broken down into 3 parts, 1 bit is the sign bit, 8 bits is the exponent (bias 127) and 23 bits is the mantissa. Working must be showed.

a. Show the binary representation of -65.75, using the IEEE-754 32-bit SinglePrecision.

b. Show the hexadecimal representation of the above answer.
