Did you figure it out?

Solution: One third of 24 is 24 ÷ 3 = 8 students, so there are 8 students in the percussion group. Half of 24 is 12, so there are 12 students in the choir group. That leaves 24 – 8 – 12 = 4 students in the guitar group.

 

 

 

 

 

 

 

 

 

 

 

Did you figure it out?

Solution:   We can solve this problem with a system of equations in which x represents the number of students in sculpture class and y represents the number of students in drawing class.

x = 1.25y

x = y + 15

We can solve this by reasoning that since x = x, that means that 1.25y = y + 15. If we solve for y, we find that y = 60. There are 60 students in drawing class.
