Answer: 90 textbooks
Step-by-step explanation:
everytime you multiply the number of students you multiply the books by the same number. to find how many times 72 was multiplied you divide it by 12.
72 ÷ 12 = 6
then multiply the original number of books (15) by 6.
15 * 6 = 90
so for every 72 students the school orders 90 textbooks
