The skirmish was over. Nine people were killed and forty-three were injured. There were four hundred fifteen people involved in the skirmish. What percent of the total people involved, to the nearest whole percent, were either killed or injured?
9 + 43 = 52
52/415 = 0.1253 = 13%
To find the percentage of people who were either killed or injured in the skirmish, we need to determine the total number of people affected and then calculate the percentage.
First, add the number of people killed (9) and the number of people injured (43) to find the total number of people affected: 9 + 43 = 52.
Next, divide the total number of people affected by the total number of people involved in the skirmish (415) and multiply the result by 100 to find the percentage: (52 / 415) * 100 = 12.53%.
To round this percentage to the nearest whole percent, we look at the decimal portion: 0.53. If the decimal portion is less than 0.5, we round down; if it is 0.5 or greater, we round up. In this case, 0.53 is greater than 0.5, so we round up.
Therefore, approximately 13% of the total people involved in the skirmish were either killed or injured.
