-2$$\frac{2}{3}$$ = -$$\frac{8}{3}$$
2$$\frac{1}{3}$$ = $$\frac{7}{3}$$
-15$$\frac{3}{7}$$ = -$$\frac{108}{7}$$
(-48) : $$\frac{4}{15}$$ = -48 $$\cdot$$ $$\frac{15}{4}$$ = -$$\frac{48 \cdot 15}{4}$$ = -12 $$\cdot$$ 15 = -180
-$$\frac{108}{7}$$ - (-180) = -$$\frac{108}{7}$$ + 180 = $$\frac{-108 + 180 \cdot 7}{7}$$ = $$\frac{-108 + 1260}{7}$$ = $$\frac{1152}{7}$$
$$\frac{7}{3}$$ $$\cdot$$ $$\frac{1152}{7}$$ = $$\frac{7 \cdot 1152}{3 \cdot 7}$$ = $$\frac{1152}{3}$$ = 384
-$$\frac{8}{3}$$ + 384 = $$\frac{-8 + 384 \cdot 3}{3}$$ = $$\frac{-8 + 1152}{3}$$ = $$\frac{1144}{3}$$ = 381$$\frac{1}{3}$$
Ответ: 381$$\frac{1}{3}$$
