7 1/3 + 3 5/6 + 4 6/8 = tolong dibantu ya

[tex]7 \frac{1}{3} + 3 \frac{5}{6} + 4 \frac{6}{8} \\ = 7 \frac{1}{3} + 3 \frac{5}{6} + 4 \frac{3}{4} \\ = (7 + 3 + 4) \frac{4 + 10 + 9}{12} \\ = 14 \frac{23}{12} \\ = 14 + 1 \frac{11}{12} \\ = 15 \frac{11}{12} [/tex]

Kalau mau disederhanakan lagi masih bisa.
