So i think in the school there may be 4800 in the school. Hope this helps
I did this with a pencil and no calculator while my daughter was practicing her driving. Please let me know if you have trouble reading it. You'll have to add the calculator stuff yourself.
Answer:
(a) 2ab - a/b
(b) c² + d + 2cd
(c) c + c²
(d) Let x be the number that is 1 greater than b, then x = b + 1
Let y be the number twice as large as b, then y = 2b
Then the quotient of x and y is what we want. This is (b + 1)/2b
(e) pq - 3(p + q)
(f) The quotient of n² and n³ + 5, this is
n²/(n³ + 5)
