Inversely means they're on opposite sides of the fraction (meaning one is the numerator, one is the denominator). So:
8/10 = 6/Y
8Y = 60
Y = 60/8 = 7.5
The answer is C.
8/10 = 6/Y
8Y = 60
Y = 60/8 = 7.5
The answer is C.

Your answer is INCORRECT.
The correct formula is:
k=xy
k= 8*10
k=80
y=80/x
y=80/6
simplify the fraction to y=40/3.
