50/240 = ≈20.83%
Rounded to 2 decimal places.
A fraction like 50/240 can show up when 50 items out of a group of 240 meet a certain condition. For example, it could represent 50 students out of 240 choosing the same lunch option, or 50 defective products in a shipment of 240.
You can picture 50/240 as a little more than one-fifth of the whole, since one-fifth is 20%. That makes it easy to estimate as about 20.83%, or roughly 21 out of every 100 items.
A common mistake is to think 50/240 is close to 50%, because the numerator is 50. The denominator matters just as much, so 50 is being compared with 240, not with 100.
