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.
In the division problem 0.28 divided by 0.7 the decimal needs to move how many places to the right?
0.4
How do you change a number from scientific notation to decimal notation?
If the exponent is positive, you move the decimal point to the right, the specified number of digits. For a negative exponent, you move it to the left. In either case, you fill out missing digits with zero. Examples (using "^" for power):3.448 x 10^1 = 34.485 x 10^6 = 5000000 (note the implied decimal point to the right of the number)3 x 10^-3 = 0.003

Why do you move the decimal to divide a decimal by a decimal?

What do you do when there is a decimal on the outside of division house?
To divide decimal numbers:If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.Divide as usual. ...Put decimal point directly above decimal point in the dividend.Check your answer.
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.
How do you divid 00.5 diviser by 00.57?
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

How do you devide with a decimal?
There are several ways. My preference with terminating decimals, is to carry out the division using the divisor without a decimal point. Then if the divisor had n digits after the decimal point, it is to move the decimal point in the quotient n places to the left.So, to calculate 18/4.32,first find 18/432 = 0.0416... with the 6 repeating4.32 has two digits after the decimal point so move the decimal point two digits to the left to give the final answer as 4.16 with the 6 repeating.
