1/10 of Mrs. Bergere's students will get this question wrong. If she has 250 students,write in scientific notation how many people will get this right.

Thank you for the opportunity to help you with your question!

If 1/10 of the students will get the question wrong, then 9/10 will get it right. Since there are 250 students, the number of students who will get the question right is 250 x (9/10) = 225.

Now, change the answer to scientific notation:

225 = 2.25 x 10^2

So, 2.25 x 10^2 students will get the question right.

Please let me know if you need any clarification. I'm always happy to answer your questions.
