Suppose that x is inversely proportional to b. If x = 3 when b = 16, find x when b = 8. Express your answer as a fraction.

i guess "inversely proportional" = "anti-proportional".

 x value x = 3 x = 6 b value b = 16 b = 8

x * y = k constant

3 * 16 = 48 <<<< k constant

b * x = 48, we know that b = 8

-> 8x = 48 -> x = 6.

Expressing 6 as a fraction: $$x = \frac{6}{1}$$.
