10/55 = ≈18.18%
Rounded to 2 decimal places.
A fraction like 10/55 can show up when 10 out of 55 people choose the same option in a survey, or when 10 of 55 items in a shipment are damaged. This amount is about 18.18%, so it represents a little less than one-fifth of the total.
To picture it quickly, imagine dividing 55 objects into five nearly equal groups of 11. Ten objects make up slightly less than one of those groups, so 10/55 is just under 20%.
A common mistake is to read 10/55 as 10.55 or assume it is exactly 20%. The numbers must be treated as a ratio, and since the numerator is a little smaller than one-fifth of the denominator, the percentage is slightly below 20%.
