Why does dividing by 10 shift each digit one place to the right?

Clear Check A (Each digit represents 10 less. B (Each digit represents 10 more. C (Each digit represents 110 110 of its previous value. D (Each digit represents 10 times its original value.

If we divide 123 b 10 we get 12.3

Consider the 1 in 123. It represents 100. After we divide the 1 in 12.3 now represents 10.

The 2 in 123 represents 20 but after the division the 2 in 12.3 now represents 10.

Therefore each digit after the division represents 1/10 of what it did. Put another way each digit in the answer represents 10 times less.
