Answer:
77
Step-by-step explanation:
percentage Students
78%-------------- -273
100%-------------- ---X
(100x273)/78 = 350 students in class so
how many did not pass?
350-273 = 77 students not pass
I guess maybe 5/35 because there are only 5 chances that you could get one of the 5 in the 35 people
12 would be considered a natural number, whole number, and an integer
Hope this helped
