To find the number of students who suggested a rainbow-themed party, we can set up a proportion:
3/8 = x/40
Cross multiplying, we get:
8x = 3 * 40
8x = 120
Dividing both sides by 8, we find:
x = 15
So, 15 students suggested a rainbow-themed party.
To find the number of students who did not suggest a rainbow-themed party, we subtract the number who suggested from the total number of students:
40 - 15 = 25
Therefore, 15 students suggested a rainbow-themed party, while 25 students did not.
