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 1696 by the denominator 66 (which you can enter in any calculator):
1696 (numerator) ÷ 66 (denominator) = 25.7
And finally, you get 25.7 as your answer when you convert 25 46/66 (or 1696/66) to a decimal.
