42/640 = ≈6.56%
Rounded to 2 decimal places.
A value like 42/640, or about 6.56%, can show up in everyday situations such as a small portion of students choosing a particular club or a few defective items in a large shipment. It describes a part that is noticeable but still fairly small compared with the whole.
To picture it quickly, imagine a group of 100 people: 6.56% would be about 6 or 7 people. Since 42 is much smaller than 640, you can estimate that the fraction is a little more than 6%, but clearly less than 10%.
A common mistake is to read 42/640 as 42%, focusing only on the numerator. The denominator matters because it tells you the size of the entire group, so 42 out of 640 is very different from 42 out of 100.
