Which of the following statements is the correct one.
1. q is jointly proportional to p and r and inversely proportional to s.
2. q is directly proportional to s and inversely proportional to p and r.
3. q is jointly proportional to s and r and inversely proportional to p.
4. q is directly proportional to r and inversely proportional to p and s.
5. q is jointly proportional to p and s and inversely proportional to r.

(1) Convert the proportionality statement into an algebraic equation, based on the definitions of jointly and inversely proportional.

p+=+k%2A%28qr%2Fs%29

(2) Solve the equation for q. "k" is just some constant, so you can still use "k" for the constant of proportionality.

q+=+k%2A%28ps%2Fr%29

(3) Convert this algebraic proportion equation into words, similar to what is given originally.
