To solve the equation \( 2 \frac { 1 } { 4 } = \frac { x } { 2 } + t \leq 1 \frac { 1 } { 6 } \), first convert the mixed numbers to improper fractions. \( 2 \frac{1}{4} = \frac{9}{4} \) and \( 1 \frac{1}{6} = \frac{7}{6} \). Now, you have the equation \( \frac{9}{4} = \frac{x}{2} + t \) and the inequality \( \frac{x}{2} + t \leq \frac{7}{6} \). To isolate \( \frac{x}{2} \), rearrange to \( \frac{x}{2} = \frac{9}{4} - t \). Next, substitute this into the inequality: \( \frac{9}{4} - t \leq \frac{7}{6} \). This allows you to visually see the relationship between \( t \) and \( x \) as you solve these equations in tandem. Want to dive into a fun historical tidbit? Did you know that fractions have been used since ancient Egypt, around 1800 BC? They used a method that involved unit fractions (fractions with numerator 1), which looked totally different from how we think about fractions today! As for real-world applications, fractions are vital in cooking, construction, and even in finance! For instance, when measuring ingredients, a chef often needs to adjust recipes based on serving sizes, which involves adding or manipulating fractions to get everything just right. It's amazing how these little numbers can impact our daily lives!
