    • No offense, but I see that your solution to this answer is a bit rather tedious than I had anticipated. How I thought of it was:

      just taking the product of the first two numbers, and carry the solution through so you end up with:

      1/10 of 1000 which is 100.

      A bit more in depth explanation:

      1/2 * 2/3 * 3/4 * 4/5 * 5/6 * 6/7 * 7/8 * 8/9 * 9/10 * 1000

      ^ is basically how to look at this, and we can see that

      1/2 * 2/3 = 1/3

      1/3 * 3/4 = 1/4

      1/4 * 4/5 = 1/5

      ...

      1/9 * 9/10 = 1/10

      1/10 * 1000 = 100

      That's how I arrived at the solution.
