3. 15 means \( \frac{2}{5} \times 15 \). Multiply the numerator and the whole number. The numerator of the fraction is . The whole number is \( \frac{2}{5} \times 15=\frac{\square \times \square}{5}=\frac{\square}{5} \)

The numerator of the fraction is 2. The whole number is 15. So when you multiply, it looks like \( \frac{2 \times 15}{5} \). Now let's calculate that: \( \frac{30}{5} = 6 \). So, \( \frac{2}{5} \times 15 = 6 \). What a neat way to show how fractions and whole numbers can work together! You can use this process for other fractions and whole numbers too. Just remember to multiply the fraction's numerator by the whole number and keep the denominator the same. It's like introducing teamwork among numbers!
