_suggest rainbow
_did not suggest rainbow
To find the number of students who suggested a rainbow theme party, we need to calculate three-eighths (3/8) of 40.
Step 1: Calculate 3/8 of 40.
(3/8) * 40 = 3 * 5 = 15
So, 15 students suggested a rainbow themed party.
To find the number of students who did not suggest a rainbow theme party, we subtract the number of students who suggested a rainbow theme from the total number of students.
Step 2: Calculate the number of students who did not suggest a rainbow theme party.
Total number of students - Number of students who suggested a rainbow theme party
40 - 15 = 25
So, 25 students did not suggest a rainbow themed party.
To find the number of students who suggested a rainbow-themed party, we can use the given ratio of three out of every eight students.
First, let's find how many students suggested a rainbow theme:
Number of students = (3/8) * 40
Number of students = 15
So, 15 students suggested a rainbow-themed party.
To find the number of students who did not suggest a rainbow-themed party, we can subtract the students who suggested from the total number of students:
Number of students who did not suggest = Total number of students - Number of students who suggested
Number of students who did not suggest = 40 - 15
Number of students who did not suggest = 25
Therefore, 25 students did not suggest a rainbow-themed party.
To find out how many students suggested a rainbow-themed party, we need to calculate three-eighths of 40, since three of every eight students suggested this theme.
To do this, we can follow these steps:
1. Multiply 40 by 3: 40 * 3 = 120.
2. Divide the result by 8: 120 / 8 = 15.
Therefore, 15 students suggested a rainbow-themed party.
To find out how many students did not suggest a rainbow-themed party, we can subtract this number from the total number of students.
Subtracting 15 from 40 gives us:
40 - 15 = 25.
So, 25 students did not suggest a rainbow-themed party.
