20/30 = ≈66.67%
Rounded to 2 decimal places.
A value like 20/30, or about 66.67%, can show up when 20 out of 30 students finish an assignment, 20 of 30 seats are filled, or 20 of 30 questions are answered correctly. It describes a little more than two-thirds of a total.
To picture it quickly, imagine a group divided into three equal parts. About two of those parts would be included, with just a small extra amount beyond two-thirds.
A common mistake is treating 20/30 as exactly two-thirds when it is being used as a precise measurement. Since 20 and 30 can both be divided by 10, the fraction simplifies to 2/3, but its decimal or percentage form keeps going and is only approximately 66.67%.
