Answer 1

5. 3 / 0.1 = 30 students

6. 49 / 0.2 = 245 lbs

Answer 2

5. There were 30 students in that class.

6. Drew weighed 245 pounds at the start.

Explanation:

5. Since 3 students are absent in which represents 10% of the classroom, multiply the number 3 by 10 to get 30 students which represents the full roster.

6. 20% of his original weight is 49, multiply that number by 5 to get the original weight which is 245 pounds.
