Answer:
81/64 or 1 17/64
Step-by-step explanation:
A negative exponent means to flip the fraction
(8/9) ^-2
(9/8)^2
81/64
Changing this to a mixed number
1 17/64
1/50
Because first you do the 0.02 = 2/100
It's over 100 because of the amount of digits.
Then simplify 2/100. Half of 2 is 1 and half of 100 is 50.
Sorry if that didn't really help, but i wanted to try.
