240/300 = 80%
A value like 240 out of 300, or 80%, can show up in everyday life when 8 out of every 10 items meet a goal. For example, a student might answer 240 of 300 practice questions correctly, or a store might sell 240 of 300 tickets.
You can picture 80% as four-fifths of a whole, with most of the amount filled in and a smaller section left over. A quick estimate is to imagine a 100-square grid with about 80 squares shaded, leaving about 20 unshaded.
A common mistake is thinking that 240 out of 300 is closer to 70% because both numbers are large. The important point is the relationship between the two numbers, not their size, and 240 is four-fifths of 300.
