Ifa * b is defined as “half the average of a and b”, determine the positive
difference between: (3 * 5) * 6 and 3 * (5 * 6). Express answer as a fraction in
simplest form or as an exact decimal.

If $\displaystyle a*b=\frac{1}{2}(\frac{a+b}{2})$
Then $\displaystyle a*b=\frac{a+b}{4}$
So $\displaystyle 3*5=\frac{3+5}{4}=2$
And $\displaystyle 2*6=\frac{2+6}{4}$
The rest should follow.
