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: \(x = \frac{6}{1}\).
