Which Quotient is Correct? Using Multiplication and Addition to Help You

In mathematics, division is a fundamental operation that involves sharing a certain number of items into equal groups or finding the number of times a certain number is contained within another number. However, when dealing with division, we often encounter remainders, which can be a bit tricky to understand. In this article, we will explore how to use multiplication and addition to help us determine the correct quotient in a division problem.

Understanding Division with Remainders

When we divide a number by another number, we are essentially finding how many times the divisor fits into the dividend. However, if the divisor does not fit evenly into the dividend, we are left with a remainder. The remainder is the amount left over after the divisor has been divided as many times as possible.

For example, let's consider the division problem $68 \div 12$ . We can see that 12 fits into 68 a total of 5 times, with a remainder of 8. This can be represented as $68 = 12 \times 5 + 8$ . This is where multiplication and addition come into play.

Using Multiplication to Help You

To determine the correct quotient in a division problem, we can use multiplication to help us. Let's consider the division problem $68 \div 12$ again. We know that 12 fits into 68 a total of 5 times, with a remainder of 8. We can use multiplication to help us find the correct quotient.

Multiplication Table

Let's create a multiplication table to help us find the correct quotient.

12	12 x 1	12 x 2	12 x 3	12 x 4	12 x 5	12 x 6	12 x 7
12	24	48	72	96	120	144	168
68	76	92	108	124	140	156	172

As we can see from the multiplication table, 12 x 5 = 60, which is less than 68. This means that 12 fits into 68 a total of 5 times, with a remainder of 8.

Using Addition to Help You

Now that we have used multiplication to help us find the correct quotient, let's use addition to help us confirm our answer.

Addition Table

Let's create an addition table to help us confirm our answer.

60	60 + 8	68
60	68	68

As we can see from the addition table, 60 + 8 = 68, which confirms our answer.

In conclusion, using multiplication and addition can help us determine the correct quotient in a division problem. By creating a multiplication table and an addition table, we can confirm our answer and ensure that we have the correct quotient.

Now that we have used multiplication and addition to help us determine the correct quotient, let's look at the options provided.

A. $68 \div 12 = 6 \, r \, 6$ B. $68 \div 12 = 6 \, r \, 4$ C. $68 \div 12 = 7 \, r \, 6$ D. $68 \div 12 = 5 \, r \, 8$

Based on our calculations, we can see that the correct quotient is $68 \div 12 = 5 \, r \, 8$ . This is because 12 fits into 68 a total of 5 times, with a remainder of 8.

The correct answer is D. $68 \div 12 = 5 \, r \, 8$ .
Quotient Quandaries: A Q&A Guide to Division with Remainders

In our previous article, we explored how to use multiplication and addition to help us determine the correct quotient in a division problem. However, we know that division can be a complex and nuanced topic, and there may be many questions and concerns that arise. In this article, we will address some of the most common questions and concerns related to division with remainders.

Q: What is a remainder in division?

A: A remainder is the amount left over after the divisor has been divided as many times as possible. For example, if we divide 17 by 5, we get a quotient of 3 with a remainder of 2.

Q: How do I determine the correct quotient in a division problem?

A: To determine the correct quotient in a division problem, you can use multiplication and addition to help you. Create a multiplication table to find the product of the divisor and the quotient, and then add the remainder to the product to get the dividend.

Q: What is the difference between a quotient and a remainder?

A: The quotient is the result of dividing one number by another, while the remainder is the amount left over after the divisor has been divided as many times as possible.

Q: Can a remainder be negative?

A: No, a remainder cannot be negative. A remainder is always a non-negative integer.

Q: How do I handle division problems with decimals?

A: When dividing a decimal by another decimal, you can use long division or a calculator to find the quotient and remainder.

Q: Can I use a calculator to find the quotient and remainder?

A: Yes, you can use a calculator to find the quotient and remainder. Most calculators have a built-in division function that can handle decimal numbers.

Q: What is the relationship between the quotient and the remainder?

A: The quotient and the remainder are related in that the quotient is the result of dividing the dividend by the divisor, and the remainder is the amount left over after the divisor has been divided as many times as possible.

Q: Can I use the quotient and remainder to find the original dividend?

A: Yes, you can use the quotient and remainder to find the original dividend. Simply multiply the quotient by the divisor and add the remainder to get the original dividend.

Q: What are some common mistakes to avoid when working with division with remainders?

A: Some common mistakes to avoid when working with division with remainders include:

Forgetting to include the remainder in the final answer
Not using the correct divisor or dividend
Not checking the quotient and remainder for accuracy
Not using a calculator or other tools to help with calculations

In conclusion, division with remainders can be a complex and nuanced topic, but with practice and patience, you can become proficient in handling these types of problems. By using multiplication and addition to help you determine the correct quotient, and by understanding the relationship between the quotient and the remainder, you can confidently tackle even the most challenging division problems.

Here are some common division problems with remainders that you can practice:
