Answer:

Step-by-step explanation:


Total students = 198
Students who travelled by bus= 198-6 = 192
Assuming that each bus had an equal amount of students we can see that:
192/4 = 48 students in each of the 4 busses
The team can miss no more than (less than or equal to) 4 chances to score a point.
Number 3 is x=5 and number 4 is x=63
He can change 1/6 and 1/3 to make their denominators 12, so it would be 2/12 and 4/12
