∙ 7y agoBecause 0.10 = 1/10 and multiplying by 1/10 is the same as dividing by 10. The two operations are inverses of one another.

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.
Are the numbers on the right side of the decimal point the decimal numbers?
yes. any thing you have on the right side of the decimal point(.) is a decimal:)
Why can you move the decimal point in the divisor to th right as long as you move the decimal point in the dividend the same number of places 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.

What is the difference between multiplying decimals and multiplying whole numbers?
You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (BEFORE eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.
What does multiplying a decimal number by 100 do to the decimal point?
It moves the decimal point two places to the right.
How do you align decimals when multiplying?
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.
Why can you move the decimal point in the divisor 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.
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 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.
Are the numbers on the right side of the decimal point the decimal numbers?
yes. any thing you have on the right side of the decimal point(.) is a decimal:)

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.
What are the roles of transferring the decimal point to the right or to the left?
Multiplying or dividing by ten.
