One unit to a unit which is a multiple of ten times as small.
To the right.
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.
If we are moving from a large value to a small value we move the decimal point to the left.

Make the divisor a whole number by moving the decimal point to the right and move the decimal point in the dividend to the right the same amount; now do the division. For example to divide 19.67 by 3.5: to make 3.5 a whole number, move decimal point 1 place to the right to give 35, so move decimal point of 19.67 to the right one place to give 196.7 Now do 196.7 divided by 35 to give 5.62 Example: to divide 196 by 2.5: To make 2.5 a whole number, move the decimal point 1 place to the right to give 25, So move the decimal point of 196 to the right 1 place to give 1960. Now do 1960 divided by 25 to give 78.4 When moving the decimal point in the dividend to the right, if you run out of digits before you've moved enough places, add zeros so that the decimal point moves the correct number, for example: To divide 1234.5 by 2.345: To make 2.345 a whole number the decimal point must move right 3 places to give 2345 so move decimal point of 1234.5 right 3 places, but after 1 place we have 12345 with 2 more places to move, so add 2 zeros to give 1234500 Now divide 1234500 by 2345.
by moving the decimal two place 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.
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.
If we are moving from a large value to a small value we move the decimal point to the left.
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.
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.
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.
why does multiplying numbers by ten move the decimal point to the right
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.
There are 10 millimetres in one centimetre. Therefore, to convert a value, such as 7.63 centimetres, to metres, you multiply by 10 to get 76.3 millimetres - thus moving the decimal point 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
