150/240 = 62.5%
A fraction like 150/240 can describe everyday situations such as completing 150 pages of a 240-page book or attending 150 minutes of a 240-minute event. In percentage terms, that means you have finished 62.5% of the total.
To picture 62.5%, imagine filling five out of every eight equal sections. It is a little more than half, but clearly less than three-quarters, so you can estimate it as being around 60% at a quick glance.
A common mistake is to treat 62.5% as if it means 62.5 whole items, even when the total is different. The percentage describes the part of the specific whole, so the actual number represented depends on what the total amount is.
