Using chart which says Dallas is 999. Conjecture: The 9 in the hundreds place in Dallas’s area is ten times as great as the 9 in the ones place of its area.

Question

Has to do with conjectures.

Answer 1

999=900+90+9.

9 in the hundreds place has a value 900.

9 in the ones place has a value 9.

10 times the 9 in the ones place is 90 so this not the same value as 900.

The conjecture is false.
