The fraction 18/51 is equal to 35.29% when converted to a percentage. This percentage is rounded to the nearest two decimal places for simplicity. The fraction represents a part-to-whole relationship, where 18 is the numerator (part) and 51 is the denominator (whole).
In everyday situations, percentages are often more intuitive and easier to understand than fractions. For example, if you were told that 18 out of 51 people in a group preferred a certain option, it might be clearer to say that about 35% of the group had that preference. This makes it easier to compare with other percentages or to visualize the proportion quickly.
