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 6904 by the denominator 46 (which you can enter in any calculator):
6904 (numerator) ÷ 46 (denominator) = 150.09
And finally, you get 150.09 as your answer when you convert 150 4/46 (or 6904/46) to a decimal.
