Question 1145241
<br>
If C and c are the same, and J and j are the same, then the answer is simple:<br>
c checkers = j jacks = m marbles.<br>
However, since that answer is trivial, and since both C and c, and both J and j, are used in the statement of the problem, I will assume C and c are not necessarily the same, and that J and j are not necessarily the same.<br>
Then the answer can be found by multiplying "C checkers" by unit fractions that change the units without changing the measurement:<br><pre>
                  j jacks       m marbles     C*j*m
   C checkers * ------------ * ----------- = ------- marbles
                 c checkers      J jacks       c*J</pre>
