Answer:
20 students should be on each float
Step-by-step explanation:
Number of seniors = 100
Number of juniors = 80
To find number of students that should be on each float, find highest common factor (H.C.F) of 100 and 80
Write prime factorisation of 100 and 80.
100 =
× 
80 =
× 5
So,
H.C.F(100, 80) =
× 5 = 4 × 5 = 20
Therefore,
20 students should be on each float
