one fourth of the students earned A's. There were 280 students. How many earned A's?
I got 70 for the answer but what is the percentage for that? Would it be 70%?
1/4 of 280 = 70 = 25% (70/280 * 100)
Note 1/4 = 25% (1/4 * 100)
To find the percentage, divide the number of students who earned A's by the total number of students and multiply by 100.
In this case, one-fourth of the students earned A's, and the total number of students is 280. So, the number of students who earned A's is 1/4 * 280 = 70.
To find the percentage, we divide 70 by 280 and multiply by 100: (70 / 280) * 100 = 25%.
So, the percentage of students who earned A's is 25%.
To find out the number of students who earned A's, you need to calculate one-fourth of the total number of students.
Here's how you can calculate it:
Step 1: Find one-fourth of 280 by dividing it by 4.
280 / 4 = 70
So, 70 students earned A's.
To convert this number to a percentage, you can divide the number of students who earned A's by the total number of students and then multiply by 100.
Here's how you can calculate it:
Step 1: Divide the number of students who earned A's (70) by the total number of students (280).
70 / 280 = 0.25
Step 2: Multiply the result by 100 to get the percentage.
0.25 * 100 = 25
Therefore, the percentage of students who earned A's is 25%.
