## How do you move the decimal point?

If there IS a decimal point, move it to the right the same number of places that there are 0s. When dividing by 10, 100, 1000 and so on, move the decimal point to the left as many places as there are 0s. So when dividing by 10, move the decimal point one place, by 100 two places, by 1000 three places and so on.

## Do you line up the decimals while multiplying decimals?

## How do you determine where to place the decimal point in the product?

Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product. To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.

## Why do we move the decimal point when multiplying?

### Why do you move the decimal point when multiplying by 10?

Multiplying a decimal by 10 increases the value of each digit by 10. Multiplying a decimal by a power of 10 increases the value of each digit by a number of times that is equivalent to that power of 10. When a digit's value is changed, that digit is moved to the appropriate place.

### Where will we put the decimal point in the quotient?

Notice that the decimal point in the quotient is directly above the decimal point in the dividend. To divide a decimal by a whole number, we place the decimal point in the quotient above the decimal point in the dividend and then divide as usual.

### How do you know how many decimal places to use?

For the number of decimal places stated, count that number of digits to the right of the decimal and underline it. The next number to its right is called the 'rounder decider'. If the 'rounder decider' is 5 or more, then round the previous digit up by 1.

### How can I multiply decimals?
