A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated by a line called the “divisor line”. We can use the division method help to solve this question: to get a decimal, simply divide the numerator 97 by the denominator 90 (which you can enter in any calculator):
97 (numerator) ÷ 90 (denominator) = 1.08
And finally, you get 1.08 as your answer when you convert 97/90 to a decimal.
