Which calculation would result in the decimal point moving two spaces to the right in a decimal number? the decimal number is divided by 100. the decimal number is divided by 10. the decimal number is multiplied by 100. the decimal number is multiplied by 10.

Hi! =)

So, let's make up just some decimal. 

Let's say that this decimal is 5.6. 

Now, we're going to run this little decimal of ours through a series of trials, and we shall not stop till we move this decimal 2 spaces to the right! 

We'll know when it is two spaces to the right when 5.6 is equal to 560. So, let's run them calculations...

A: 5.6 / 100 = 0.056. Nope, this won't be it...
B: 5.6 / 10 = 0.56. Nope, this again won't be it...
C: 5.6 * 100 = 560. This looks pretty good! 
D: 5.6 * 10 = 56. Nope, this isn't 560. 

So, after going through all those calculations - I think we can see what our answer will be here! =)

To move the decimal place two places to the right, you should multiply the decimal by 100. The easiest way to see this is through examples:

  .55
x100
   55

You should simply move the decimal to the right for each "0" in the problem. Then, you should multiply by whatever is left in the problem as you would solve for a normal multiplication problem.
