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 1700 by the denominator 46 (which you can enter in any calculator):
1700 (numerator) ÷ 46 (denominator) = 36.96
And finally, you get 36.96 as your answer when you convert 34 136/46 (or 1700/46) to a decimal.
