There ar 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?

Answer 1

Three out of every eight students suggested a rainbow-themed party, so the fraction that suggested this theme is 3/8.

To find out how many students suggested a rainbow-themed party, we multiply the fraction by the total number of students:
3/8 x 40 = <<3/8*40=15>>15 students.

Therefore, 15 students suggested a rainbow-themed party.

To find out how many students did not suggest a rainbow-themed party, we subtract the students who did suggest a rainbow-themed party from the total number of students:
40 - 15 = <<40-15=25>>25 students.

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