**How To Divide With Decimals** – Hello friends! Welcome to this video about dividing decimals! Dividing decimals may not seem like the most useful tool, but it comes in handy in many situations in everyday life.

Now you’re wondering if dividing decimals is ever useful. Let’s say you had $26.84 in your checking account and wanted to buy gas for your car without going over your budget. It costs $3.69 a gallon and you want to tell the attendant how many gallons you want to put in your car. How many gallons of gas do you need?

Or say you’re building a house and need lumber 4.85 feet long. A local store sells giant trees that are 28 feet tall. In the store, you wonder: how many trees can be cut from each beam?

Your first step is to write the problem just like any other long division problem. It should look like this:

When solving this problem, it will be much easier to work with whole numbers instead of decimal numbers.

The easiest way to do this is to multiply each number in the expression by 10. As a rule of thumb, every time you multiply a number by 10, you basically move the decimal point one place to the right. If we multiply .5 and 4.5 by 10, we get:

Now you will solve (45div 5) as usual. This is a relatively simple problem, so we don’t need to go through the long division steps. (5 times 9=45).

You may be wondering if we need to do anything to change this answer. Finally, we have changed two numbers in our expression. How can the answer be correct in our original expression? However, if you pull out your calculator, you’ll see that when we divide 4.5 by .5, our original expression will be 9, just like dividing 45 by 5.

The first step is to multiply each number by 10 to convert these decimal numbers to whole numbers. As for 3.5, this will give us 35. But if we look at the second number in our expression, 15.75, we realize that multiplying it by 10 is not enough. This gives us 157.5, which is still not a number. So what do we do in this case?

Remember the basic rule for dividing numbers by decimals – you have to do the same thing for both numbers in the expression. To make 15.75 a whole number, we need to multiply it twice by 10, or say by 100. It actually moves the decimal point two places to the right, making it 1575.

As we mentioned, we have to do the same thing for both numbers, so now we multiply 3.5 by 10 twice (or by 100). We move the decimal point two places to the right and add a zero to fill the empty space. Now we have (1, 575div 350).

The problem now is the long division. 350 does not occur in 1, 15, or 157, so estimate how many times it occurs in 1, 575. 350 is about 3 times out of 1,000, so 4 is a good estimate of how many times. Enter 1, 575. Let’s do a quick multiplication to double check. (3504 times).

So, we multiply (4times 0=0) and (4times 5) to get (20). (2), (4 times 3=12) and then we add (2) which gives us (14). So we have (1, 400) which is ideal where (1, 575) is going to go. Now we write (4) over (5) and we have (1, 575-1, 400), leaving (175).

Now we divide (1, 750div 350) by trial and error. Before that, if we look at (350 seed 4=1, 400), we can see that (350 seed 5) gives exactly (1, 750), which means That we add. a (5) is after the decimal point, right before our (4). This gives us the final answer (4.5).

Remember that dividing by decimals may seem difficult at first, but it’s basically just like regular long division. Don’t forget the strategy for converting decimals to whole numbers: Multiply both numbers in the expression by multiples of 10 to move the decimal point as close as possible. Treat both numbers as the same and you will have the correct answer.

## Division Of Decimals By 2 Digit Number

Decimals When two numbers are multiplied by 10, the denominator is no longer a decimal. Then divide by length in general. Place the decimal point directly above the decimal point.

When dividing a decimal by a whole number, divide the whole number in the same way as the whole number is divided by itself, but place the decimal point in the answer where it is in the original number.

Divide the decimal by long division, and if there is a decimal in the denominator, be sure to multiply by multiples of 10. Place the decimal point directly above the fraction.

To divide a decimal using a formula, first assign the dividend to the first number. Then round the other number groups in the divisor. The number of groups that have been circled is your answer or quote.

If there is a remainder when dividing the decimal, add a zero to the end of the decimal and divide until the remainder remains.

The correct answer is 4.79. To divide a decimal by a whole number, divide by the same length as dividing by two whole numbers, but put the decimal in the same place in the answer as the dividend.

The correct answer is 0.7185. To divide a decimal by a whole number, divide by the same length as dividing by two whole numbers, but put the decimal in the same place in the answer as the dividend. If it is not evenly divisible, add 0 to the end of the division and divide until there is no remainder.

The correct answer is 230.9. First, multiply both numbers by 10 to remove the decimal point in the denominator.

The correct answer is 3, 738. First multiply both numbers by 1,000 and remove the decimal point in the denominator.

The correct answer is 22.15. First, multiply both numbers by 100 to remove the decimal point in the denominator. 2 Decimal Multiplication Step 1: Hide the numbers so that there are no decimals. Do not add “0” as a placeholder. A whole number was Step 3: Count the number of decimal places in each number. Step 4: The total shows how many decimal places your answer has.

Step 1: List 407 + 12 210 as if there were no decimals Step 2: Multiply 12 617 as if there were whole numbers

Step 3: Count the number of decimal places in each number. x 3.1 + 1 decimal 407 + 12 210 . 12 617 3 decimal places Step 4: The total shows how many decimal places your answer has.

## Math Review With Decimals

5 Dividing Decimals Rule 1: The denominator can never be a decimal. It must be an integer. Rule 2: If you must carry a decimal point in the denominator (outer number). Rule 3: After moving the decimal, move the decimal UP to your answer.

5 Rule 2: If you have to carry a decimal point in the denominator (outer number), you must carry a decimal point in the denominator (inner number). 2 2 . 64. 9 -4 4 2 0 -1 98 11 -110 Rule 3: After moving the decimal point to the dividend, move the decimal point UP to your answer.

When solving any division problem, it is important to know which number is the division and which number is the division.

## Dividing Decimals By Decimals (annexing Zeros)

Remind yourself of long division steps, as we will need them when dividing decimals.

Now it’s time to do the math. To do this, we ask ourselves, “How many times does the divisor go into division?”

Then we multiply the denominator by a number that is equal to or close to the denominator and subtract it from the dividend. Then we skip the next number and repeat the process.

Now it’s time to talk about both of them
