Question

The morning announcements said that two out of every seven sixth-grade students in the school have an overdue library book. Jasmine said, "Since there are 84 6th grades, that would mean 32 of us have overdue books!" Is Jasmine correct? Explain why or why not. I really need help I'm not that good at math.

Answer 1

Answer: Jasmine is wrong because $\dfrac27$ of  84 is 24 not 32.

Step-by-step explanation:

GIven: In the morning announcements, $\dfrac27$ of sixth-grade students in the school have an overdue library book.

If there are 84 6th grade students, then the number of students have overdue library books = $\dfrac27\times 84 = 2\times 12=24$

i.e. 24 of 6th-grade students have overdue books.

But Jasmine said 32 of 6th-grade students have overdue books which is wrong.
