why is it true if you multiply a whole number just to add a zero at the end ??

Question

This is my homework and I really need the answer

 

Answer 1

Hi Alanna;

If you have the number 5, and you want it to be 50, you multiply 5 times 10.

If you have the number 34, and you want it to be 340, you multiply 34 times 10.

 

If you have the number 75, and you want it to be 7500, you multiply 75 times 100.

And so on...

Does this answer your question?  If not, please let me know.
