10-3*9/14-4*13/14+2*8/14

10 - 3 * 9 : 14 - 4 * 13 : 14 + 2 * 8 : 14 Решаем по действиям:  1. 3 * 9 = 27  2. 27 : 14 = [latex]\frac{27}{14}[/latex] 3. 4 * 13 = 52 4. 52 : 14 = [latex]\frac{26}{7}[/latex] 5. 2 * 8 = 16 6. 16 : 14 = [latex]\frac{8}{7}[/latex] 7. 10 - [latex]\frac{27}{14}[/latex] = [latex]\frac{113}{14}[/latex] 8. [latex]\frac{113}{14}[/latex] - [latex]\frac{26}{7}[/latex] = [latex]\frac{61}{14}[/latex] 9. [latex]\frac{61}{14}[/latex] + [latex]\frac{8}{7}[/latex] = [latex]\frac{11}{2}[/latex] = 5.5 Ответ: 5.5
