What is the first step in solving for X when forming a proportion?

The first step in solving for X when forming a proportion is to identify the known values in fraction format. This is foundational because proportions are equations that state two ratios are equal. By clearly recognizing the known values, you can set up the proportion correctly, which is essential for solving for the unknown variable X.

When you identify the known values, you can effectively organize the information in a way that allows you to cross-multiply or apply other algebraic methods to isolate X. This step is crucial because it lays the groundwork for any further calculations or manipulations needed to solve the equation.

The approach of converting values to decimals, estimating, or guessing does not establish the necessary mathematical relationship required to solve for X effectively. These methods may lead to inaccuracies or confusion rather than providing a structured pathway to determine the value of the unknown. Thus, starting with the identification of known values ensures a clear and logical progression toward finding the solution.
