2 1 per 5 + 1 1 per 10= pakai jalanya kaya ap

[tex]-2 \frac{1}{5} = \frac{11}{5} \\ -1 \frac{1}{10} = \frac{11}{10} \\ \\ \frac{11}{5} + \frac{11}{10} \\ = \frac{2 \times 11 + 11}{10} \\ = \frac{22 + 11}{10} \\ = \frac{33}{10} \\ = 3 \frac{3}{10} \\ = 3.3[/tex]
Maaf Kalau Salah

21/5+11/10=310/10+11/10=321/10
