Question
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 eight students suggested a rainbow-themed party. How many students suggested a rainbow-themed party? How many did not?(1 point)
students suggested a rainbow-themed party, while
students did not.

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.
