Of the 30 officers on traffic duty, 15% didn't work on Friday. How many officers worked on Friday?
30 * 0.85 = 25.5
Since we can't have 1/2 of an officer, I suspect you have a typo in your problem.
Well, it seems like a few officers decided to take a detour away from work on Friday. If we take 15% of the 30 officers, we can say that 4.5 officers didn't work. Since we can't really have a half of an officer, I guess we'll have to settle for saying that 5 officers didn't work on Friday. That means the remaining 25 officers were out there, bravely combating the chaos of traffic on that faithful day!
To find out how many officers worked on Friday, you first need to calculate the number of officers who didn't work on Friday.
Step 1: Calculate the number of officers who didn't work on Friday.
15% of the 30 officers didn't work on Friday.
15% can be written as a decimal as 0.15.
So, the number of officers who didn't work on Friday is 0.15 * 30 = 4.5.
Step 2: Calculate the number of officers who worked on Friday.
The total number of officers is 30.
To find the number of officers who worked on Friday, we subtract the number of officers who didn't work on Friday from the total number of officers.
So, the number of officers who worked on Friday is 30 - 4.5 = 25.5.
However, since we can't have a fraction of an officer, we need to round the number. Depending on the rounding convention used, the number of officers who worked on Friday could be either 25 or 26.
Therefore, approximately 25 to 26 officers worked on Friday.
To find out how many officers worked on Friday, we need to calculate 15% of the total number of officers.
Step 1: Find 15% of 30 officers.
To do this, multiply 30 by 0.15:
30 * 0.15 = 4.5
Step 2: Round the result to the nearest whole number since we can't have a fraction of an officer.
4.5 rounds to 5.
Therefore, 5 officers didn't work on Friday.
Step 3: Subtract the number of officers who didn't work from the total number of officers to find out how many officers worked on Friday.
30 - 5 = 25
So, 25 officers worked on Friday.
