Left.

For positive powers: The rule is to move the digits in the place value columns left (for multiplication) or right (for division) the same number of columns as the power of 10. However, on paper this is not easy to do so the effect on the decimal point relative to the digits is used instead: move the decimal point the same number of digits right (for multiplication) or left (for division); if there are less digits than required to be moved, insert zeros until the decimal point has moved the required number of digits. If the power is negative reverse the direction of movement (eg with moving the decimal point, to multiply move the decimal point left and divide by moving the decimal point to the right).

It's 540. The easiest way to multiply 10 or 100 or 1000 or 10000 etc. by a decimal is to look at the number of zeros in the number and move the decimal to the right the same amount of times as the amount of zeros I am multiplying the number by. For instance if I am multiplying 3.5 by 10 I would move the decimal in 3.5 to the right one time because there is one zero in 10. Changing it from 3.5 to 35. If you were multiplying it by 100 you would move the decimal 2 times because there are 2 zeros in 100, with 1000 you would move it three times and so on. If you were dividing it you would do the same thing just move the decimal to the left instead. Hope this information helps you in the future.

120. the simple way to answer this is by moving the decimal two places to the left and then multiplying by 3. also by multiplying 4000 by .03.

Exactly as in the question.A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Zeros after the decimal point are inappropriate because they imply a greater degree of precision and there is no justification for that.Exactly as in the question.A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right.

Move the decimal point, the same number of places as the power of 10. That way ---> to multiply. This way <--- to divide.

What do you mean if you mean in multiplication after multiplying move the decimal to the left for how many numbers there were after the decimal point. if you mean in addition or subtraction the you line up the numbers and then the point stays where it was Ex. 2.13 +31.4 --------- 43.53 If you mean in division then the easiest way is to move the decimal point to the right of the divisor however many times you wish and you have to do the same with the dividend and after dividing that you have to replace however many times you move the decimal point

Left.

You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (BEFORE eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.

If you have a fraction, divide the top by the bottom to get the decimal. If you have a decimal, move the decimal point 2 places that way --> to get the percent. If you have percent, move the decimal point 2 places this way <-- to get the decimal.

Left or right.

Dividing by 0.1 is the same as multiplying by 10, and the simple way to multiply any whole number by 10 is to add a 0 on the end. If the number to be multiplied is shown with a decimal point, just move the decimal point one place to the left.

If you have a decimal, move the decimal point two places that way ---> to get percent.

Take the number of centimeters, move the decimal point 2 places this way and you have centimeters.

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.
