- The problem asks to find the unknown value \(x\) in the equation \(\frac{1}{2} = \frac{x}{14}\).
- Multiplying both sides by \(14\) isolates \(x\).
- Calculating \(14 \times \frac{1}{2}\) results in \(7\).
- The final answer is \(\boxed{7}\).
Explanation
- Problem Analysis
We are given the equation \(\frac{1}{2} = \frac{x}{14}\), where \(x\) represents the unknown value in the box. The objective is to determine the value of \(x\) that makes this equation true. This involves solving for \(x\) by isolating it on one side of the equation. We can use the concept of equivalent fractions, which states that if \(\frac{a}{b} = \frac{c}{d}\), then the equation can be solved by multiplying both sides by a common factor or by using cross-multiplication.
- Solving the Equation
To isolate \(x\), we multiply both sides of the equation \(\frac{1}{2} = \frac{x}{14}\) by \(14\). This gives us:
\[14 \times \frac{1}{2} = 14 \times \frac{x}{14}\]
\[\frac{14}{2} = x\]
\[7 = x\]
Thus, the value in the box is \(7\).
Examples
Imagine you are following a recipe that calls for 1/2 of a cup of flour, but you only have a measuring tool that measures in 14ths of a cup. To ensure you have the correct amount, you set up the equation \(\frac{1}{2} = \frac{x}{14}\). By solving this, you find that you need \(x=7\) portions of 1/14 cup to get the equivalent of 1/2 cup of flour. This demonstrates how proportional relationships help in cooking and resource management.
