## What happens when you move the decimal to the right?

If you have to move the decimal point to the right to get the original number, the exponent will be a positive number, if you have to move the decimal point to the left to get the original number, the exponent will be a negative number..

## How do you move the decimal point when multiplying?

Move the decimal point two places to the right to find the product. To multiply a decimal number by a power of ten (such as 10, 100, 1,000, etc.), count the number of zeros in the power of ten. Then move the decimal point that number of places to the right.

## How do you divide a decimal by 100?

To divide a whole or a decimal number by 100, move the decimal point two places to the left. Note that although a whole number does not have a decimal point, we can always add it at the end of the number. (For example, 35 and 35.

## How do you divide step by step?

The steps are more or less the same, except for one new addition:Divide the tens column dividend by the divisor.Multiply the divisor by the quotient in the tens place column.Subtract the product from the divisor.Bring down the dividend in the ones column and repeat.

## How do you divide if the divisor is a decimal?

To divide decimal numbers: Multiply the divisor by as many 10’s as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10’s.

## What is the decimal rule?

The same rule applies if there are decimals. Add them first, then units, then tens and so on. The most important rule to remember is to line up the decimal points in your calculation, ensuring that the decimal point in the answer also lines up with the decimal points above it.

## How do you split 100 3 ways?

Well, you can divide it mathematically, you just did. 33.333… is a valid answer. Because of the way your calculator writes numbers it can’t be represented in a finite number of digits, but it’s still a number. If you think about it as a fraction, 100 divided by 3 is 33+(1/3).

## How do you move a decimal point?

Move the decimal point to the left when dividing a decimal number by a power of 10 number. As with multiplying decimals by power of 10 numbers, count the number of zeros to know how many spaces to move the decimal, but move the decimal in the opposite direction.

## Why does multiplying numbers by 10 move the decimal point to the right?

When multiplying a decimal by 10 the amount of zeros increased from the right (naturally) making the decimal point go to the right.

## How do you divide decimals step by step?

How to Divide DecimalsMove the decimal point in the divisor and dividend. … Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.

## How many times do you move the decimal when dividing?

So when you divide by powers of ten (ten times itself some number of times, like ten, one hundred, one thousand, etc.), the decimal moves to the left. For each power of ten, you move one place to the left. So if you divided a number by one hundred (10^2 or 10*10), you would move two places to the left.

## What are the four rules of decimals?

You should become efficient in using the four basic operations involving decimals—addition, subtraction, multiplication, and division.

## Which is the same as dividing a number by 1 000?

There is a similar shortcut for multiplying decimal numbers by numbers such as 10, 100, and 1000: Move the decimal point to the right as many places as there are zeros in the factor. Move the decimal point one step to the right (10 has one zero). Move the decimal point two steps to the right (100 has two zeros).
