For the information given in the statement let:
*C the million metric tons of rice that China produces per year
*P the million metric tons of rice that Philippines produces per year
So, you have
[tex]\begin{gathered} C=kP \\ \text{ Where k is the number of times the annual rice production of the Philippines} \\ 196=k\cdot16 \\ \text{ Divide by 16 into both sides of the equation} \\ \frac{196}{16}=\frac{k\cdot16}{16} \\ 12.25=k \end{gathered}[/tex]Therefore, annually China produces 12.25 times the amount of rice that the Philippines produces.
