Compare the values of the underlined digits 2783 and 7283 with two being the underlined digit.

In the first case, the 2 is in the place for thousands, and it means 2 000 (two thousand).
In the second case, 2 is in the place for hundreds, and it means 200 (two hundred).

The difference between them is 180! (or 10% of the first value and 1000 percent of the second value)

7p=14 so then you would divide by p=2
