If j and k are inversely proportional and j = 42 when k = 56 , what is the value of j when k = 98?
If they're inversely proportional, then \(j*k=j*k\) even when j and k are different. In this case, \(42*56=j*98\).
We would have \(j= (48*56)/98\)
Solving this, we have \(j = 24\)
(correct me if i am incorrect)
j = c/k or
jk = c c = constant
42(56) = 2352
when k = 98
j (98) = 2352
j = 2352/98 = 24 just as ahz001 found !
