Which expression is equivalent to \( \frac{12+6}{2} \) ?

First, let's simplify the expression \( \frac{12+6}{2} \). When you add the numbers in the numerator, you get \( 12 + 6 = 18 \). Now, dividing by 2 gives us \( \frac{18}{2} = 9 \). Therefore, the expression \( \frac{12+6}{2} \) is equivalent to 9! Now, here’s a little nugget of history: The notation of fractions dates back to ancient civilizations. The Egyptians used a system of unit fractions (like 1/2, 1/3, etc.), and their contributions laid the groundwork for modern arithmetic. Math has come a long way since then! And if you ever find yourself stuck with tricky fractions, try breaking them down into simpler parts! It’s like slicing a pizza: easier to handle one slice at a time rather than tackling the whole pizza in one bite. Plus, always double-check your calculations to avoid common mistakes like mixing up numerators and denominators!
