A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 55 by the denominator 34:
55 (numerator) ÷ 34 (denominator) = 1.62
As a result, you get 1.62 as your answer when you convert 1 21/34 (or 55/34) to a decimal.
