Solving the Equation: The Quotient of a Number and 18 is 109.2

Understanding the Problem

The given sentence states that the quotient of a number and 18 is 109.2. This can be translated into a mathematical equation as:

x / 18 = 109.2

where x is the unknown number.

Analyzing the Equation

To solve this equation, we need to isolate the variable x. We can start by multiplying both sides of the equation by 18 to eliminate the fraction.

x = 109.2 * 18

This will give us the value of x.

Using the Division Property of Equality

The division property of equality states that if two fractions are equal, then their cross-products are also equal. In this case, we can use the division property of equality to solve the equation.

x / 18 = 109.2

Multiplying both sides by 18 gives us:

x = 109.2 * 18

This is the same as the previous step.

Using the Multiplication Property of Equality

The multiplication property of equality states that if two expressions are equal, then their products are also equal. In this case, we can use the multiplication property of equality to solve the equation.

x / 18 = 109.2

Multiplying both sides by 18 gives us:

x = 109.2 * 18

This is the same as the previous step.

Checking the Statements

Based on the analysis above, we can conclude that:

It can be solved by using the division property of equality.
It can be solved by using the multiplication property of equality.

Therefore, both statements are correct.
