Problem:

Let x= (0.6)(0.60). When x is written out as a decimal, what is the sum of the first 15 digits after the decimal point?

LISTEN TO THIS PART:  (The 6 in 0.6 has a repeating sign on that ONE digit) 

(The 60 in 0.60 has a repeating sign over BOTH digits)!!! THANKS!

If you write the first 15 digits (not counting 0) of the first decimal, you get .666666666666666. The second is .606060606060606. If you add them together, you get 1.27 with a repeating bar over the 2 and 7.

Hope this helps!
