Often, you will find your calculator is your friend when working problems like these.
If you want to work it by hand, convert all mixed numbers to improper fractions. Then multiply the numerator by the reciprocal (inverse) of the denominator.
= (5/2)/(5/8) . . . . convert numerator to improper fraction
= (5/2)*(8/5) . . . . invert the denominator and multiply
= (5/5)*(8/2) . . . . rearrange to aid simplification
= 4
The quotient is 4.

Answer: D) reflection across y = -x
Explanation:
When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).
When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is
So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).
Similarly, B(1,5) moves to B ' (-5, -1)
Finally, C(6,9) becomes C ' (-9, -6)
