d) \( 3 \cdot 2+\frac{2}{5} \)

Let's do some math magic! First, we multiply \(3 \cdot 2\) to get \(6\). Now, we add \(\frac{2}{5}\) to that. To combine these numbers more easily, we can think of \(6\) as \(\frac{30}{5}\). So, we have \(\frac{30}{5} + \frac{2}{5} = \frac{32}{5}\). Voila, the final answer is \(\frac{32}{5}\) or \(6.4\) if you prefer the decimal version! Now, if you're wondering how this kind of math flashes into your everyday life, think about cooking! Recipes often need you to scale up or down. For instance, making a double batch of cookies involves simple calculations like this one. Mastering fractions can help you tweak those delicious desserts to just the right amount!
