There are 40 students in Joan's class. She plans to invite them to her birthday party. She asked them to suggest a theme for her party. Three of every 8 students suggested a rainbow-themed party. How many did not?
Three out of every 8 students suggested a rainbow-themed party, so the remaining students did not suggest a rainbow-themed party which is 8 - 3 = <<8-3=5>>5 students.
Since Joan has 40 students in her class, therefore those who did not suggest a rainbow-themed party is 5/8 * 40 = <<5/8*40=25>>25 students. Answer: \boxed{25}.

To find the number of students who did not suggest a rainbow-themed party, we'll first calculate the number of students who did suggest it.
Three out of every eight students suggested a rainbow-themed party. We can calculate the number of students who suggested it by multiplying the ratio of students who suggested it by the total number of students.
Number of students who suggested a rainbow-themed party = (3/8) x 40
Calculating this expression:
(3/8) x 40 = 3 x 5 = 15
So, 15 students suggested a rainbow-themed party.
To find the number of students who did not suggest a rainbow-themed party, we'll subtract this number from the total number of students:
Number of students who did not suggest a rainbow-themed party = Total number of students - Number of students who suggested a rainbow-themed party
Number of students who did not suggest a rainbow-themed party = 40 - 15 = 25
Therefore, 25 students did not suggest a rainbow-themed party.
To find out how many students did not suggest a rainbow-themed party, we first need to determine how many students did suggest a rainbow-themed party.
Given that three out of every eight students suggested a rainbow-themed party, we can calculate the number of students who did suggest it by taking three-eighths of the total number of students:
(3/8) * 40 = 15
Therefore, 15 students suggested a rainbow-themed party.
To find out how many students did not suggest this theme, we subtract the number of students who did suggest it from the total number of students:
40 - 15 = 25
Therefore, 25 students did not suggest a rainbow-themed party.
