Multiply 12 By 4.$12 \times 4 = 48$Write A Story Problem To Match The Equation $36 \div 5 = 7 \text{ R } 1$.
Introduction
In mathematics, multiplication and division are two fundamental operations that help us solve various problems in our daily lives. While multiplication involves finding the product of two or more numbers, division involves finding the quotient of two numbers. In this article, we will explore how to create story problems that match multiplication and division equations.
Multiplication Story Problem
Let's start with a simple multiplication story problem. We have already seen an example of a multiplication equation: . Now, let's create a story problem that matches this equation.
Tom's Toy Cars
Tom has 12 toy cars that he wants to display on a shelf. Each shelf can hold 4 toy cars. How many shelves will Tom need to display all his toy cars?
To solve this problem, we need to multiply the number of toy cars (12) by the number of toy cars each shelf can hold (4). This will give us the total number of shelves Tom needs.
So, Tom will need 48 toy cars to fill all the shelves.
Division Story Problem
Now, let's move on to a division story problem. We have already seen an example of a division equation: . Now, let's create a story problem that matches this equation.
Samantha's Cookies
Samantha has 36 cookies that she wants to package in bags of 5 cookies each. How many bags can Samantha fill with the cookies she has?
To solve this problem, we need to divide the total number of cookies (36) by the number of cookies each bag can hold (5). This will give us the total number of bags Samantha can fill.
So, Samantha can fill 7 bags with 5 cookies each, and she will have 1 cookie left over.
Real-World Applications
Multiplication and division are used in various real-world applications, such as:
- Cooking: When you are cooking, you may need to multiply a recipe by a certain number of people. For example, if you are making a recipe that serves 4 people and you need to serve 12 people, you will need to multiply the ingredients by 3.
- Shopping: When you are shopping, you may need to divide a total cost by the number of items you are purchasing. For example, if you are buying 5 items that cost $36 in total, you will need to divide the total cost by the number of items to find the cost of each item.
- Travel: When you are traveling, you may need to multiply the distance between two locations by the number of people traveling. For example, if you are traveling 12 miles and you need to travel with 4 people, you will need to multiply the distance by the number of people.
Conclusion
In conclusion, multiplication and division are two fundamental operations that help us solve various problems in our daily lives. By creating story problems that match multiplication and division equations, we can make these operations more meaningful and relevant to our lives. Whether you are cooking, shopping, or traveling, multiplication and division are essential skills that you need to master.

Frequently Asked Questions
In this article, we will answer some frequently asked questions about multiplication and division.
Q: What is the difference between multiplication and division?
A: Multiplication is the process of adding a number a certain number of times, while division is the process of sharing a certain number of items into equal groups.
Q: How do I multiply two numbers?
A: To multiply two numbers, you need to add the first number a certain number of times, equal to the second number. For example, to multiply 4 and 5, you need to add 4 together 5 times: 4 + 4 + 4 + 4 + 4 = 20.
Q: How do I divide two numbers?
A: To divide two numbers, you need to share the first number into equal groups, equal to the second number. For example, to divide 12 by 4, you need to share 12 into 4 equal groups: 12 ÷ 4 = 3.
Q: What is the order of operations?
A: The order of operations is a set of rules that tells you which operations to perform first when you have multiple operations in an expression. The order of operations is:
- Parentheses: Evaluate expressions inside parentheses first.
- Exponents: Evaluate any exponential expressions next.
- Multiplication and Division: Evaluate any multiplication and division operations from left to right.
- Addition and Subtraction: Finally, evaluate any addition and subtraction operations from left to right.
Q: How do I handle remainders in division?
A: When you divide a number by another number and get a remainder, you can represent the result as a mixed number or an improper fraction. For example, if you divide 17 by 5, you get 3 with a remainder of 2. You can represent this result as a mixed number: 3 2/5.
Q: What are some real-world applications of multiplication and division?
A: Multiplication and division are used in various real-world applications, such as:
- Cooking: When you are cooking, you may need to multiply a recipe by a certain number of people. For example, if you are making a recipe that serves 4 people and you need to serve 12 people, you will need to multiply the ingredients by 3.
