Answer: [tex]\frac{b}{50}[/tex]
Step-by-step explanation:
Given: The total number of students donated books in Hannah's school = 150
The number of books donated by students = b
The average number of books each student donated=[tex]\frac{\text{total books donated}}{\text{total students}}[/tex]
Thus, The average number of books each student donated=[tex]\frac{b}{150}[/tex]
Since, Hannah donated 3 times as many as the average number of books each student donated.
Then , the number of books donated by Hannah= [tex]3\times\frac{b}{150}=\frac{b}{50}[/tex]
