To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.

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

0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.

Multiplying or dividing by ten.

It is because 0.10 = 1/10 and so multiplication by 0.10 is the same as division by 10, the opposite of multiplication by 10.

Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.

The decimal point is moved to the left by the value of the power.

two.

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.

To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.

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.

Write the number out completely. Locate the decimal point. Move the decimal point left by one digit. You have multiplied the number by 0.1 Example: Multiply 293.56 by 0.1 Move decimal point left one position: 29.356
