[tex]3 \frac{1}{5} + 4 \frac{2}{10} [/tex]

[tex]3 \frac{1}{5} = \frac{16}{5} \\ \\ 4 \frac{2}{10} = \frac{42}{10} \\ \\ \frac{16}{5}+\frac{42}{10} =... \frac{16x10}{5x10} + \frac{42x5}{10x5} = \frac{160}{50} + \frac{210}{50} = \frac{370}{50} = 7 \frac{20}{50} \\ \\ [/tex]

Semoga membantu & tidak salah jawaban saya :)
