One foot is equal to 12 inches. The question is asking: 5 inches is what fraction of 12 inches. This is the same thing as 5 being the numerator and 12 being the denominator. This is 5/12. Therefore your answer is: 5 inches is 5/12 of a foot. Hope this helps! Please rate, leave a thanks, and mark a brainliest answer (not necessarily mine). Thanks, it really helps! :D
