2. \( \frac{9}{12}=\frac{\square}{4} \)

To solve the equation \( \frac{9}{12} = \frac{\square}{4} \), you can cross-multiply. This means you'll multiply the numerator on the left by the denominator on the right and the denominator on the left by the numerator on the right. This gives you \( 9 \times 4 = 12 \times \square \). Simplifying this results in \( 36 = 12 \times \square \). Dividing both sides by 12 gives you \( \square = 3 \). Now that you know your missing value is 3, it's like uncovering a little treasure in the land of fractions! This approach helps when checking for equivalent fractions. Just remember, fractions are all about balancing—keep your scales even and you'll get it right every time!
