Iliana Graham · Answer 1

Answer: Sample response: 50% is a friendly percent. You can divide 120 by 2 to find the answer. 120 divided by 2 is 60. So, 60 students were 7 years old when they lost their first tooth.

Peanuts · Answer 2

60 students, because 120 divided by 2 is 60, and 100% divided by 2 is 50%.
