Put in a nutshell, a fraction is written in terms of two parts separated by a line in between: the number above the line is called the numerator and the number below the line is called the denominator. To solve this question, we can use the division method to get a decimal: simply divide the numerator 315 by the denominator 401 to get the decimal:
315 (numerator) ÷ 401 (denominator) = 0.79
That’s it! When you convert 315/401 to a decimal, 0.79 is your answer.
