- 6целых 2/3-8,75-2целых 5/12. Помогите пожалуйста

6 $\frac{2}{3}$ - 8.75 - 2 $\frac{5}{12}$ =
6 $\frac{2*4}3*4}$ - 8 $\frac{75}{100} - 2 [tex] \frac{5}{12}$ =
6 $\frac{8}{12}$ - 2 $\frac{5}{12}$ - 8 [tex] \frac{75}{100} =
4 [tex] \frac{3*25}{12*25} - 8 [tex] \frac{75*3}{100*3} =
4 [tex] \frac{75}{300} - 8 [tex] \frac{225}{300} =
- 4 [tex] \frac{150}{300} = - 4 [tex] \frac{1}{2}
