What else can I help you with?
What do you do if the decimal point is in the dividend?
Divide as normal, but make sure to place the decimal point in the quotient directly above the decimal point in the dividend.
How do you divide to the hundredths place?
To divide to the hundredths place, first perform the division as you normally would, placing the decimal point in the quotient directly above the decimal point in the dividend. Continue dividing until you reach at least two decimal places in the quotient. If necessary, you can add zeros to the dividend to find additional decimal places. Finally, round the result to the hundredths place if it has more than two decimal places.
How do you know where to place the decimal point in long division with decimals?
In long division with decimals, you place the decimal point in the quotient directly above the decimal point in the dividend (the number being divided). If the divisor has a decimal, you can move the decimal point to the right until it becomes a whole number, and you must do the same with the dividend. After aligning the decimal points, proceed with the division as you would with whole numbers.
How does the position of the decimal point change in a quotient as you divide by increasing powers of 10?
The decimal point moves to the left.
Explain how estimating the quotient helps you place the first digit in the quotient of a division problem?
Estimating the quotient involves rounding the dividend and divisor to make mental calculations easier. By determining how many times the rounded divisor fits into the rounded dividend, you can identify the first digit of the quotient. This estimation provides a starting point, guiding you to a more precise calculation and helping to ensure that the division process remains manageable. Ultimately, it helps you gauge the size of the final answer.

Divide as normal, but make sure to place the decimal point in the quotient directly above the decimal point in the dividend.
Why is estimating important when dividing with decimals?
Using an estimate ensures that the answer is about right. With decimals where the decimal point should go is difficult for a lot of people, so an estimate of the answer ensures that it is put in the right place.
How can estimating products help you to place a decimal correctly?
By estimating the product it gives an indication of how big the final answer should be; knowing this, the decimal point can be put in to give an answer of the correct size. For example if the product estimate is 125 and the actual answer (without the decimal point) is 136728, then the decimal point needs to be inserted to make the answer about 125; the place is therefore after the 136, making the answer 136.728 (= 5.4 x 25.32 ≈ 5 x 25 = 125)
How do you divide to the hundredths place?
To divide to the hundredths place, first perform the division as you normally would, placing the decimal point in the quotient directly above the decimal point in the dividend. Continue dividing until you reach at least two decimal places in the quotient. If necessary, you can add zeros to the dividend to find additional decimal places. Finally, round the result to the hundredths place if it has more than two decimal places.
How can you use estimation to place the decimal point in the quotient 42.56 divided by 22?
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
How can estimating quotients help you place the decimal correctly?
Estimating quotients gives an indication of the order of magnitude of the answer. That is, whether the answer is in units, or tens, or hundreds, thousands and so forth. Basic understanding of the placement of the decimal point should then be a trivial exercise.
How do you know where to place the decimal point in long division with decimals?
In long division with decimals, you place the decimal point in the quotient directly above the decimal point in the dividend (the number being divided). If the divisor has a decimal, you can move the decimal point to the right until it becomes a whole number, and you must do the same with the dividend. After aligning the decimal points, proceed with the division as you would with whole numbers.
How do you divide with decimals in the dividend?
Put the decimal point for the quotient exactly above the decimal point in the dividend. Then forget about it, and just keep your digits lined up as you do the division. The decimal point winds up exactly where it belongs in the quotient.
In witch place would you write the first digit of the quotient for 2.682 divided by 4?
0.6705
How does the position of the decimal point change in a quotient as you divide by increasing powers of 10?
The decimal point moves to the left.
How does the position of the decimal point change in a quotient as you divide by increasing powers of ten?
With each increase in the power of ten, the decimal point moves one place to the left. You may have to insert os immediately after the decimal point to maintain that shift.
In which place would you write the first digit of the quotient for 2.682 divided by 4?
0.6705
