e) \( 4+\frac{1}{3}+\frac{2}{5}= \)

Let's break it down! To solve \( 4 + \frac{1}{3} + \frac{2}{5} \), first, convert the fractions to have a common denominator, which is 15. So, \( \frac{1}{3} = \frac{5}{15} \) and \( \frac{2}{5} = \frac{6}{15} \). Now we can easily add them: \( 4 + \frac{5}{15} + \frac{6}{15} = 4 + \frac{11}{15} \), which gives us \( 4 \frac{11}{15} \). And there you have it! Math can be like a puzzle, where each piece (or number!) fits together perfectly. So next time you encounter mixed fractions, just think of them as fun building blocks forming your final answer!
