6/30 = 20%
A value like 6/30, or 20%, can show up in everyday life when 6 out of 30 students choose the same lunch, 6 of 30 products are on sale, or 6 of 30 seats are empty. It describes a smaller portion of a larger group.
To picture it quickly, imagine a group split into five equal parts. This amount is about one of those five parts, so it is easy to estimate as roughly one-fifth of the whole.
A common mistake is thinking 6/30 is 6% because the numerator is 6. The denominator matters because it tells you the total number being considered, so the same 6 items would represent a different percentage in a group of 60 or 10.
