Help!

Inversely proportional means basically that the product of the numerator and denominator will always be the same. So if the fraction is \(\frac{16}{21} = \frac{j}{k}\), the product of \(16\times21 = 336\). We are trying to find \(j\) if \(k = 14\). We have \(\frac{16}{21} = \frac{j}{14}\). You can solve this by doing \(336\) divided by \(14\), which gives you \(24\). \(j = 24\).

Thanks Daisy!!!!....here's another way

j  = C / k      where C is the proportionality constant

And we know that

16 = C / 21      multiply both sides by 21

336  = C

So  when  k = 14  we have that

j = 336 / 14  =   24
