Question

There are 48 students. 8 are sick, one-fifth of the remaining students sent cards to them. How many students wrote cards? Please explain

Answer 1

Since there are 48 students and 8 of them are sick you subtract 48-8. Which equals 40 students. Then, you multiply 40 by 1/5 and get 8. So 8 students wrote cards. 

Answer 2

8 students sent them because when you do 48 - 8 = 40

Then , you divide the denominator 5 and divide it by 40 and you get 8
