Answer: 70 % of students did their homework last week.
Step-by-step explanation:
Given :
Total students = 300
Students who did their homework = 210
Percentage of students who did their homework = [tex]\frac{\text {Students who did their homework}}{\text {Total students}}\times 100\%[/tex]
Putting the values we get:
Percentage of students who did their homework = [tex]\frac{210}{300}\times 100\%=70\%[/tex]
Thus 70 % of students did their homework last week.
