                      RATES in JOB%2FDAYS

pedro and juan       1%2F%283%263%2F7%29

pedro                1%2Fp

juan                 1%2Fj

The most important thing to do is be able to form this system of equations.:1%2Fp%2B1%2Fj=7%2F24%2C%281%2Fp%29%2A3%2B%281%2Fj%29%2A4=1

Why the whole thing does not render, I don't know. The system in pure text is this:
1/p+1/j=7/24 and (1/p)*3+(1/j)*4=1.

Everything after that is arithmetic.
