1. None of them.

"10 times greater than x" means x, plus x 10 more times -- i.e., 11x. The place values of the 5's in the given numbers are either 5, 50, or 500; none of those numbers is 11 times another of them.

If you mean "10 times AS GREAT", then again the place values are either 5, 50, or 500. Find one pair where the values of the two 5s are 5 and 50, or 50 and 500.

2. The value of the "7" in 270 is 7*10 = 70. The value of the "7" in 207 is 7*1 = 7. 70 is 9 times greater than 7. (70 = 7+63 = 7 + 9 times 7, so 9 times GREATER THAN 7). 70 is clearly 10 TIMES AS GREAT AS 7; it's not 10 times GREATER THAN 7.
