35% wouldn't be an improper fraction - it would be a proper fraction. 35/100, or 7/20 is the proper fraction answer. An improper fraction is where you have a larger number as a numerator and a smaller number as the denominator, such as 100/35.

Percent or per cent means per 100 so 35 percent as a fraction is 35/100. We can simplify this fraction to 7/20. So 7/20 or 35/100 is equivalent to 35 percent.

35 percent is equal to 35 parts of 100, or 35/100. Cancelling this down to a fraction in its lowest terms, by dividing both sides of the fraction by 5, this is equal to 7/20, or seven twentieths.

0.35 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its rational equivalent is 35/100 which can be simplified, if required.
