C# project for class

Hello,

I am very new to programming as I am only a few weeks into my C# class. I have a project and after reading and reading my book, sadly I am stuck. Here is what the project calls for: I need to create a program that converts inches as an input to feet, yards and miles as an out put. I need to set all of the values to two points after the decimal and use constants, variables and separate methods to accomplish this task.
I have an idea as how to start the program and how to use constants and variables but am confused as how to use various methods to accomplish this task. Again I am sure this is basic stuff and has become frustrating that I am in need of help. I do have a desire to learn this and become good at it. If anyone can help me not just complete the project but ultimately understanding of programming it would be greatly appreciated.
