Answer:
10%
Step-by-step explanation:
1200-1080= 120 , 1200/10 is 120 which means 10% is 120 students , so if you subtract 120 from 1200 you get 1080.
The percentage decrease in the number of students is -10%.
Given that,
- The school has 1,200 students last year.
- And, this year it is 1,080.
Based on the above information, the calculation is as follows:
[tex]= \frac{1080 - 1200}{1200} \\\\= -10\%[/tex]
Therefore we can conclude that the percentage decrease in the number of students is -10%.
