Mathematics

Step-by-step explanation:

5 2/3 + (-2 5/6)

$=\frac{17}{3}-\frac{17}{6}\\\\=\frac{17*2}{3*2}-\frac{17}{6}\\\\=\frac{34}{6}-\frac{17}{6}\\\\=\frac{34-17}{6}\\\\=\frac{17}{6}\\\\=2\frac{5}{6}$

2 5/6 + (- 1 3/4) = 2 5/6 - 1 3/4

$\frac{17}{6}-\frac{7}{4}\\\\=\frac{17*2}{6*2}-\frac{7*3}{4*3}\\\\=\frac{34}{12}-\frac{21}{12}\\\\=\frac{34-21}{12}\\\\=\frac{13}{12}\\\\=1\frac{1}{12}$
