Because the marble is not replaced and that affects the next event where another marble is chosen.
<span>Total number of students: 115 + 225 + 140 = 480 Number of buses needed: 480 ÷ 80 = b
b = 6</span>
1/3 in 6th grade......1/3 = 0.33 = 33% in 6th grade
35% in 7th grade
(100% - (33% + 35%) = 100% - 68% = 32%
most students : 7th grade
fewest students : 8th grade
