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)

1 answer

To determine how many students suggested a rainbow-themed party, we can set up a proportion:

3/8 = x/40

Cross-multiply:

8x = 3 * 40

8x = 120

Divide both sides by 8:

x = 120/8 = 15

So, 15 students suggested a rainbow-themed party.

To determine how many students did not suggest a rainbow-themed party, we can subtract the number of students who suggested a rainbow-themed party from the total number of students:

40 - 15 = 25

Therefore, 25 students did not suggest a rainbow-themed party.
