Identify the floating point numbers corresponding to the following single precision machine binaries:

1: 0 10000001 01100000000000000000000

2: 0 01111111 00000000000000000000000

3: 0 01111011 10011001100110011001100

Hello, can someone please explain how to approach these? My biggest area I need clarity, when I get the exponent (such as number 1 having an exponent of 2), how do you get to the final answer from there? That is where I need a lot of clarity, thank you!
