It's bad pedagogy. But it is also technically incorrect. You can have fractions with complex numbers.

Good point! I’m not a mathematician so the pedagogy here doesn’t really irk me. But, I do also believe that teachers should be held to a higher standard, especially when writing out educational text. Thanks for the clarification!

Also, I bet the authors weren’t intentionally trying to lead readers astray with that statement. Most books have a preface with some point of contact if you find errors. I’m sure if you wrote in the authors would be happy to fix this up :)
