You don't move the decimal point at all. You just multiply the numbers and the point should sort itself out or be put of how many digits it is to be.

Why does multiplying numbers by 10 move the decimal to the right but multiplying numbers By .10 you move the decimal to the left?
0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
When multiplying two factors that each have 1 decimal place place the decimal point in the product places to the left?
two.
What is the general rule for multiplying a decimal by a negative integer power of 10?
The decimal point is moved to the left by the value of the power.
Why do you add a decimal point in math with numbers?
To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
When multiplying two factors that each have one decimal place place the decimal point in the product how many places to the left?
Two places.
Which way do you move the decimal point when multiplying?
left
When you are multiplying a decimal with 10 does the decimal point move left or right?
right
Why does multiplying numbers by 10 move the decimal to the right but multiplying numbers By .10 you move the decimal to the left?
0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
What are the roles of transferring the decimal point to the right or to the left?
Multiplying or dividing by ten.
Why does multiply numbers by 10move the decimal point to the right but multiplying by zero point Tian move the decimal point to the left?
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.
Which pattern describe how the decimal point moves when you multiply a decimal number by any power of ten?
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.
When multiplying two factors that each have 1 decimal place place the decimal point in the product places to the left?
two.
What is the general rule for multiplying a decimal by a negative integer power of 10?
The decimal point is moved to the left by the value of the power.
Why does multiplying numbers by 10 move the decimal point to the right?
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.
Why do you add a decimal point in math with numbers?
To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
What is it called when you move a decimal point 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.
What is the rule for multiplying by 0.1?
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
