When dividing a decimal by a decimal why is it sometimes necessary to add a zero to the right of the decimal point in the quotient?

Because when you want to divide a decimal by a larger number, like 3 divided by 5, you need to add a zero to make the 3, 30, so you can divide, but then the quotient has to be a decimal because 5 does not go into 3 evenly

How many decimal points do you move when dividing by 10?
You move decimal one place to the left when dividing by ten You move decimal two places to the left when dividing by 100 You move decimal three places to the left when dividing by 1000, etc...
How do you place the decimal point in the quotient when dividing a decimal by a whole number?
The decimal point goes in the quotient the moment you reach the decimal point in the dividend and need to use the digit in the tenths column. When using the "Bus stop" method, the digits will line up so that the decimal point goes in the quotient directly above the decimal point in the dividend.Using the Bus stop method, it is easiest to put the decimal point in the quotient above the decimal point in the dividend first (before any any division calculation is done) and then do the division by ignoring the decimal points and putting digits in the quotient as normal; except if once all the digits of the dividend have been used there is a non-zero remainder, zeros can be added to the end of the dividend as they are trailing zeros after a decimal point which make no difference to the number.eg dividing 1.2 by 5:First place the decimal point in the quotient over the decimal point in the dividend:_____.___------5_|_1.2Now divide as normal:____0.2__------5_|_1.2____1 0____----______2Used up all the digits of the dividend but have a remainder, so add trailing zeros after the decimal point and finish the division:____0.24__--------5_|_1.2000____1 0____----______20______20______---_______0Only needed one extra 0, but it did not hurt putting three of them.→ 1.2 ÷ 5 = 0.24Sometimes the decimal may recur or not terminate; in that case, stop when the required level of accuracy is reached (rounding by calculating a further digit and using that as the deciding digit).
Why does dividing 5 by a decimal less than 1 give a quotient greater than 5?
5 x 0.2 = 25 Or to put it a different way 25 / 0.2 = 5 Dividing something by a number greater than 1 gives you a smaller number Dividing something by 1 gives the same number Dividing something a number smaller than 1 gives you a larger number
How can you predict whether a quotient will be a terminating decimal or a repeating decimal?
They are the same thing a non-terminating is a non-repeating decimal
When do you move the decimal point to the left?
When you are dividing.
Why is it sometimes necessary to add a zero to the right of the decimal point in the quotient when your dividing by a decimal?
significant figures. you'll learn how to use significant figures in high school chemistry.
What is a quotient as a decimal?
A quotient is the result of dividing one number by another. It can be expressed as a ratio or as a decimal.
How can you use a compatible number to estimate a quotient when dividing a decimal by a whole number?
Yes
How is dividing decimals and dividing whole numbers the same?
If you are making use of long division method, the process of dividing a whole number is actually a subset of the process of dividing the decimals. While dividing both you may get a quotient with decimal places. Some exceptions to this do exist in case of whole numbers. Like when you are dividing 100 by 2, the quotient 50 has no decimal places.
Why is it necessary to add a decimal point when you are dividing a numerator from a denominator?
It is not always necessary. For example 100/5 = 20. No decimal points in sight!
What is the rule about significant figures when multiplying or dividing measurement?
the decimal place in the quotient or product should be based in the decimal place of the given with the least significant figures
What is the outside number in a division problem called?
It is called a divisor. The inside number is called the dividend and the answer is the quotient. The leftover number is called the quotient but you can keep dividing until you get a decimal.
When dividing decimals can you have a remainder in the quotient?
the Remainder is divided by the outside number to form another decimal, which is added onto the end of the answer.
Why is it necessary to put zero when the dividend has a remainder?
If it's long division then it is because the quotient will become a decimal number after its decimal point
The qoutient of a number and 21?
The quotient of a number and 21 is the result obtained when you divide the number by 21. For example, if you divide 42 by 21, you get a quotient of 2. If you divide 63 by 21, you get a quotient of 3. And so on. The quotient can be an integer or a decimal number, depending on the numbers you’re dividing.
Why is it sometimes necessary to add a zero to the right of the decimal point in the quotient?
Because it makes the quotient in divisable by multiple cation IN KID WORDS It makes number bigger to add or divide the dividend or the number on the side go into it so always out 000ss! HOPE THIS HELPED, Kelsey
What is the decimal quotient for 19 divided by 5?
