Understanding Percentage: A Comprehensive Guide

What is the percentage of respondents who say they would visit a trampoline park?

a. 14%

b. 15.5%

c. 17%

d. 18.9%

The correct answer is: a. 14%

Explanation:

Out of 500 respondents surveyed, 70 individuals stated that they would visit a trampoline park. To calculate the percentage, we use the following method:

Total respondents = 500

100% = 500

1% = 500 ÷ 100 = 5

Since 1% of the 500 respondents is equal to 5 people, we can determine the percentage of 70 individuals by dividing 70 by 5:

70 ÷ 5 = 14

Therefore, 70 of 500 respondents saying they would visit a trampoline park corresponds to 14% of the total respondents. Hence, option 'a' is the correct choice.

What is a Percentage?

In mathematics, a percentage is a quantity or ratio expressed as a fraction of 100 (from the Latin per centum, meaning "by a hundred"). While alternative abbreviations like "pct.", "pct", and sometimes "pc" are utilized, the percent symbol, "%," is commonly employed to signify it. A percentage is dimensionless and does not have a specific unit of measurement.

In ancient Rome, calculations were frequently done using fractions that were multiples of 1/100 long before the introduction of the decimal system. For example, Augustus imposed a 1/100 tax known as "centesima rerum venalium" on commodities sold at auction. These fractions were manipulated in the same manner as percentages.
