Solution: 100/120 as a decimal is 0.83
Methods
Explanation using the division method:
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 100 by the denominator 120 (which you can enter in any calculator):
100 (numerator) ÷ 120 (denominator) = 0.83
And finally, you get 0.83 as your answer when you convert 100/120 to a decimal.
