Which expression has a value equal to 28/4
The Correct Answer and Explanation is :
The correct answer is: 7
The expression that has a value equal to ( \frac{28}{4} ) is simply ( 28 \div 4 ). This expression is a division operation, where 28 is divided by 4.
Calculation
To understand how this division works, let’s perform the calculation:
[
28 \div 4 = 7
]
This means that when you divide 28 into 4 equal parts, each part will be 7.
Concept of Division
Division is one of the four fundamental arithmetic operations, alongside addition, subtraction, and multiplication. It involves splitting a number (the dividend) into a specified number of equal parts (the divisor). In this case, 28 is the dividend, and 4 is the divisor. The result of a division operation is called the quotient.
Visualizing Division
To visualize ( 28 \div 4 ), consider the following scenario: if you have 28 apples and you want to distribute them evenly among 4 friends, you would give each friend 7 apples. This distribution demonstrates the concept of division as it emphasizes the idea of equal sharing.
Alternative Expressions
Besides ( 28 \div 4 ), there are other mathematical expressions that can yield the same result of 7. For example, you could use multiplication, such as ( 7 \times 4 ), which equals 28. Alternatively, you can express this relationship in fractional form as well, such as ( \frac{28}{4} = 7 ).
Importance of Division
Understanding division is essential not only in basic arithmetic but also in more complex mathematical concepts and real-life applications. It is used in various fields, including science, finance, and engineering. The ability to divide numbers accurately allows for effective problem-solving and decision-making in everyday situations.
In summary, the expression ( 28 \div 4 ) equals 7, demonstrating the process of dividing 28 into 4 equal parts, which each yields 7.
