Simulating rational number addition/subtraction

With guile (and a few other Schemes/Lisps) you can directly add fractions or rational numbers: (+ 1/2 1/12) => 7/12 It's like magic, no? Anyway, I'm trying -- for educational purposes -- to reproduce this functionality. But right out of the blocks I'm stuck trying to figure out how to handle inco

I've got this fork going where I've done some editing (grammar, style, spelling, etc.) on the book (up to "Reporting bugs." Let me know what you think. In general, I think Scheme desperately needs an "O'Reilly"-style book. Question: What should we say when so
