1440/2400 = 60%
A fraction like 1440/2400, or 60%, can show up in everyday life when 60 out of every 100 items meet a condition. For example, a store might sell 60% of its inventory during a sale, or a student might attend 60% of the days in a program.
You can picture 60% as a little more than half, since half is 50%. Imagine a group of 10 objects with 6 shaded, or a progress bar filled three-fifths of the way.
A common mistake is thinking 60% means 60 out of 60, when it actually means 60 out of 100. It is also easy to confuse 60% with 0.60 or with 6%, even though these represent different amounts.
