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

To add these fractions, you'll first want to find a common denominator. The least common multiple (LCM) of 3 and 5 is 15. So, convert each fraction: \( \frac{1}{3} = \frac{5}{15} \) and \( \frac{2}{5} = \frac{6}{15} \). Now, you can add them: \( \frac{5}{15}+\frac{6}{15}=\frac{11}{15} \). So, \( \frac{1}{3}+\frac{2}{5} = \frac{11}{15} \)! Fractions can be tricky, but they’re like puzzle pieces; with the right approach, they fit perfectly together!
