What is the decimal equivalent of 9 percent?

How do you write the standard number 5217000000 in scientific notation?
You move the decimal left or right until you end up with one digit in front of the decimal. Then, if you had to move the decimal to the left to get this number, you will have ten to the positive power of the number of decimal places moved. If you had to move the decimal to the right to get the number, you will have ten to the negative power of the number of decimal places moved. In this example, 5217000000 = 5.217 x 109
What is 0.75 written as a percent?

Which way would you move the decimal?
If I wanted to multiply by a power of ten, I'd move it to the right. If I wanted to divide by a power of ten, I'd move it to the left.
How is the way the decimal point moves when you divide a decimal number by a power of ten the same as when you multiply?
It is not. For positive powers of ten, the decimal point moves to the right when multiplying and to the left when dividing. For negative powers of ten the point moves in the opposite directions.
Why Move the decimal point to the right when you multiply?
The reason is because you have to make the number bigger when you multiply. When you move the decimal to the right you make the number bigger, when you move it to the left you make it smaller. Therefore, when you divide you must move the decimal to the left.
How do you multiply or divide by the powers of ten?
When multiplying by a power of ten the digits of the number move left the same number of place value columns as the power. When dividing by a power of ten the digits of the number move right the same number of place value columns as the power. As this is awkward to do with pencil and paper, the effect on the position of the decimal point is used instead: To multiply by a power of ten the decimal point is moved right the same number of digits as the power of 10; To divide by a power of ten the decimal point is moved left the same number of digits as the power of 10; If there are insufficient digits to do the moving zeros (0) are inserted as necessary.
Why do you have to move the decimal over?
When you multiply or divide a number by 10, the decimal place is moved to the right or the left. Ie. 2.0 x 10 = 20.0 ( The decimal point was moved to the right for multiplication). Ie. 20.0 / 10 = 2.0 ( The decimal point was moved to the left for division).
What happensto the place value of a number when you divide ten?

How does the position of the decimal point change in a quotient as you divide by increasing powers of ten?
With each increase in the power of ten, the decimal point moves one place to the left. You may have to insert os immediately after the decimal point to maintain that shift.
