There must be at least two chaperones for 25 students on a school trip. How many chaperones are needed for 59 students?

Question

I need to show my work too 

Answer 1

2 Chaperons for the first 25 students; 2 more Chaperons for the second 25 students --  that's 4 Chaperons for 50 students.  Now, what to do with the remaining 9?

 

Mathematically, 1 more Chaperon (total of 5) is o.k.  But, if they are assigned in pairs (that is, if no Chaperon should be alone in charge of even 9 students), then the number is 6.  And, the groups could be more evenly divided.

Answer 2

There is direct variation between no. of chaperons and no. of students because if increase the no. of students we should also increase the no. of  chaperons for them.let x  chaperons are required for 59 students. then  the ratio in both the case will be equal

 

2    x

--   =

25  59

 

x*25 = 2*59

x= (2*59) /25  =4.72 ≈ 5( in whole numbers)

 

 

Answer 3

59 ÷ 25 = 2.36

2 · 2.36 = 4.72

 

Since a 0.72 of a chaperon is not real, 5 chaperons are needed
