How do you convert 89 inches to a fraction?

Answer 1

Like all whole numbers put it over 1, to get 89/1 inches.

Perhaps you ought to ask your question with more clarity as to what you want.

For example, do you mean "How do you convert 89 inches to a fraction of another unit, for example a chain?"

In which case you find out how many inches are in the other unit (1 chain = 792 inches) and then use this as the denominator with 89 as the numerator and then simplify the fraction. In this case 89 inches is 89/792 chain.
