This reduces nicely if you first notice that 16/81 = (2/3)^4.
Then use the properties of powers (of positive real numbers):
(16/81)^(3/4) = ((2/3)^4)^(3/4) = (2/3)^3 = 8/27
The answer is 110 because 75 is 3/4 so you just get 4 (is the total ) and you divide 88/4 = 22 *3 =66 is 60%
55-90=35 theres your answer... its suspicious they give easy answers in middle school u sure thats the question?
