2¼ = (4×2+1)/4
300.
Steps:

Park p :
18/82 = 0.219 = 21.9% green birds
park q :
39/88 = 0.443 = 44.3% green birds
park r :
38/64 = 0.593 = 59.3% green birds
park service :
22/50 = 0.44 = 44%
park with greatest percentage of green birds is park r <==
So this is a BIDMAS question so first you do what’s in the brackets so you have (1-9x1-4) and you have to do the multiplication first out of that to get (1-9-4) which is -12 so then you have overall 36 / -12 + 1 + 2 so you have to do the division first so do 36/-12 to get -3 and you have -3 + 1 + 2 which is 0 so your answer is 0.
