0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
why does multiplying numbers by ten move the decimal point to the right
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.

0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
Well, when you're multiplying, you don't always have to move the decimal. It depends on the numbers you're working with. If you're multiplying by a whole number, you can keep the decimal in the same place. But if you're multiplying by a decimal, you may need to move the decimal to the right in the answer. Just remember to take your time and enjoy the process of learning new things!
This is because we count in tens so that the place value of a digit is ten times the place value of the digit to its right.
why does multiplying numbers by ten move the 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.
Yes. You first multiply, then however many decimal places you were multiplying, you move over.
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.
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
To multiply by 10, add a zero (move the decimal one place to the right.) To divide, take a zero away (move the decimal one place to the left.)
Well, honey, you move the decimal to the right when you're multiplying by powers of 10. It's as simple as that. Just count how many zeros are in the power of 10 and shift that decimal over to the right that many places. Easy peasy lemon squeezy!
