Final answer:
A percent is a way of expressing a fractional amount of something using a whole divided into 100 parts. To calculate what percent a percent bar equals, you need to determine the value the percent bar represents in relation to the whole. If the percent of positive students is 24%, then the percent bar would equal 24%.
Step-by-step explanation:
A percent is a way of expressing a fractional amount of something using a whole divided into 100 parts. A percent is a ratio whose denominator is 100. We use the percent symbol, %, to show percent.
To calculate what percent a percent bar equals, you need to determine the value the percent bar represents in relation to the whole. For example, if the percent of positive students is 24%, then the percent bar would represent 24 out of 100 parts or 24/100. Therefore, the percent bar would equal 24%.
Example:
If there are 500 students in total, then 24% of 500 equals (24/100) x 500 = 120 students. Therefore, the percent bar would represent 120 out of 500 students or 24%.
