На 15 %

Answer 2

Calculating the Percentage Decrease in the Number of Students

To calculate the percentage decrease in the number of students, we can use the formula:

Percentage Decrease = ((Initial Number - Final Number) / Initial Number) * 100

Given: Initial Number of Students = 1400 Final Number of Students = 1190

Using the formula: Percentage Decrease = ((1400 - 1190) / 1400) * 100

Percentage Decrease = (210 / 1400) * 100

Percentage Decrease = 0.15 * 100

Percentage Decrease = 15%

So, the number of students decreased by 15% over the course of the year.
