The greatest common factor of 27 and 54 is 27.
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 the party. Three of every eight students suggested a rainbow theme party. How many students suggested a rainbow themed party?
A. 3
B. 15
C. 25
D. 40
The number of students who suggested a rainbow theme party can be found by multiplying the total number of students (40) by the fraction of students who suggested a rainbow theme (3/8):

40 * (3/8) = 1.875

Since we can't have a fraction of a student, we round up to the nearest whole number. Therefore, the number of students who suggested a rainbow theme party is:

2
