What is it called when you move a decimal point to the right?
When you move a decimal point to the right you are multiplying a number by 10. For example, take 3.4. If you move the decimal point to the right you get 34. This is the same as: 3.4x10 = 34. Reversing this, you are dividing by 10 by moving the decimal point to the left. For example, take 73. If you move the decimal point to the right you get 7.3. This is the same as: 73/10 = 7.3. If you move a decimal point 2 spaces to the right, you are multiplying by 100, or more generally if you move the decimal point n spaces to the right, you are multiplying by 10^n.

What is 10 percent of 867?
10% of 867 is 86.7 All you have to do is move the decimal point one spot to the left (the decimal point starts at 867.0; by moving it one spot it becomes 86.70 or just 86.7 This is, ofcourse, for multiplying (1/10 X 867/1) but when you are dividing by 10 or 100 or 1000 you simply move the decimal point one place to the left. If the number you are dividing by has two 0's then you move the decimal point two places to the left rather than just one. The same applies for multiplying.
