Number to a multiple by a positive power of 10.
by moving the decimal two place to the right.
To divide by a decimal, make the divisor a whole number by moving the decimal point to the right; the dividend must also be changed by moving its decimal point the same number of digits to the right. So to divide 0.5 by 0.57, make the divisor 0.57 into 57 by moving the decimal point two digits to the right, then also move the decimal point of the dividend (0.5) two places to the right to give 50. Thus: 0.5 / 0.57 = 50 / 57 ~= 0.88
Multiplies it by an integral power of ten - positive if the decimal point is moved to the right and negative if moved to the left.
To change a decimal to a percentage, all you need to do is multiply it by 100. This is the same as moving the decimal point two spaces to the right. .453 = 45.3%
Moving a decimal point to the right is the same as multiplying a number by a power of ten. As long as both numbers are multiplied by the same amount, they will retain their same relationship.
by moving the decimal two place to the right.
Moving from a smaller value to a larger value.
Move the decimal point one place to the right. If the decimal point is already at the end of the number, add a 0 to the extreme right before moving the decimal point.
Moving from a smaller value to a larger value.
To the right.
Moving from a smaller value to a larger value.
Because that is how the decimal system is defined: the place value of each digit is ten times that of the digit to its right. Multiplication by 10 is equivalent to moving each digit to the its left or, equivalently, moving the decimal point to the right.
A value to its multiple by a positive integer power of 10.
To divide by a decimal, make the divisor a whole number by moving the decimal point to the right; the dividend must also be changed by moving its decimal point the same number of digits to the right.

6.02 * 100 = 602. You move the decimal point to the right by the number of zeroes after the 1. So if you multiply it by 100, the decimal moves to the right by 2 spaces.
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.
