Answer: The 7 is in the ten-thousands place, it is worth 70,000.
Explanation:
All you have to do is separate the number into all of its place values. Starting from the left you have ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, and millions.
The 7 is in the 5th place from the left, and 5th in my list is ten-thousands, therefore the 7 is in the ten-thousands place. When 7 is multiplied by 10,000, you get 70,000.
