35 in fraction form is written as 35/1. This is because any whole number can be expressed as a fraction by placing it over 1. The numerator (35) represents the number of parts we have, and the denominator (1) represents the total number of equal parts the whole is divided into.
In this case, 35/1 means that we have 35 parts out of 1, which is essentially the same as the whole number 35. This fraction is already in its simplest form since the numerator and denominator have no common factors other than 1.
