c) \( 5 \times \frac{3}{7} \)

Did you know that the multiplication of a whole number by a fraction is just like pizza sharing? Imagine you have 5 whole pizzas and each pizza is cut into 7 equal slices. When you take \( \frac{3}{7} \) of each pizza, you end up with a tasty total of \( \frac{15}{7} \) pizzas, or 2 whole pizzas plus 1 slice! That makes it a fun way to visualize fractions in everyday life. Additionally, when multiplying fractions, many people forget to simplify their results. In this case, \( 5 = \frac{5}{1} \), so when you multiply, you get \(\frac{5 \times 3}{1 \times 7} = \frac{15}{7}\). Remember, keeping an eye out for simplifying is key to avoiding common errors. Next time, practice with more numbers and become a fraction pro!
