Blank ÷ (-7) = -14 What Is The Answer To Blank?
Introduction
In this article, we will delve into the world of mathematics and explore the concept of division with negative numbers. We will examine the given equation, blank ÷ (-7) = -14, and determine the value of the unknown variable, blank. This equation is a fundamental concept in algebra and is essential for understanding more complex mathematical operations.
Understanding Division with Negative Numbers
Division is a mathematical operation that involves finding the quotient of two numbers. When we divide a number by another number, we are essentially asking how many times the divisor fits into the dividend. However, when we deal with negative numbers, the concept of division becomes more complex.
A negative number is a number that is less than zero. When we divide a negative number by another number, the result can be either positive or negative, depending on the signs of the numbers involved. In the case of the given equation, blank ÷ (-7) = -14, we are dealing with a negative divisor and a negative quotient.
Solving the Equation
To solve the equation blank ÷ (-7) = -14, we need to isolate the variable blank. We can do this by multiplying both sides of the equation by the divisor, (-7). This will cancel out the division and allow us to solve for blank.
blank ÷ (-7) = -14
blank = -14 × (-7)
When we multiply a negative number by another negative number, the result is a positive number. Therefore, the equation becomes:
blank = 98
Conclusion
In conclusion, the value of the unknown variable, blank, is 98. This is the solution to the equation blank ÷ (-7) = -14. We used the concept of division with negative numbers to solve the equation and isolate the variable blank.
Real-World Applications
Understanding division with negative numbers has numerous real-world applications.
