Balancing equations

There's a Balancing Equation question in the course reader that I was unsure about. It says the answer can be: 2C6H7N + 31/2O2 --> 12CO2 + 7H2O + N2 OR 4C6H7N + 31O2 --> 24CO2 + 14H2O + 2N2 Are both answers correct? Isn't the second answer the only acceptable one because you can't have a fraction as a coefficient?

Both answers are correct and have identical meaning. You can have a fraction as a stoichiometric coefficient, although usually it makes calculations simpler to work with whole numbers.

Although both answers are correct, it is recommended to have whole numbers for stoichiometric coefficients. On an exam, generally use whole numbers.

They are both correct. But always go with the whole numbers. Especially if its a problem involving chemical equilibrium because if you didn't use whole numbers, your K value would be incorrect.
