Question 17
Find the value of $\frac{3\times111.111}{6\times1.001}+\frac{3\times222.222}{6\times2.002}+\frac{3\times333.333}{6\times3.003}+\cdots+\frac{3\times666.666}{6\times6.006}$.
Interpretation: The dots within 111.111, 1.001, etc. are decimal points. The ellipsis means the six terms k=1 through k=6.
Answer format: enter the integer answer without units. Leading zeros are optional; the original paper uses four-digit boxes.
