Question

Выполните вычитание: 4 14/19-2 5/19=? 8 7/10-5=? 12-7/18=? 11-3 5/12=? 8 7/15-3 11/15=? 10 9/14-3 9/14=?

Answer 1

1)95-43=52

2)87-5=2

3)$\frac{18*12-7}{18}=11\frac{11}{18}$

4)$11-\frac{41}{12}=\frac{12*11-41}{12} =\frac{91}{12} =7\frac{7}{12}$

5)$\frac{127}{15} -\frac{56}{15} = \frac{71}{15} =4\frac{11}{15}$

6)$\frac{149}{14} - \frac{51}{14} = \frac{98}{14} =7$

Answer 2

Ответ:

Пошаговое объяснение:

4.14/19-2.5/19=2.9/19. 8.7/10-5=3.7/10. 12-7/10=11.3/7. 11-3.5/12= 7.7/12. 8.7/15-3.11/15=4.11/15. 10.9/14-3.9/14=7

Answer 3

Конечно, я помогу вам выполнить данные вычитания.

1. \(4 \frac{14}{19} - 2 \frac{5}{19}\):

\(4 \frac{14}{19} - 2 \frac{5}{19} = 4 - 2 + \frac{14}{19} - \frac{5}{19} = 2 + \frac{9}{19} = 2 \frac{9}{19}\).

2. \(8 \frac{7}{10} - 5\):

\(8 \frac{7}{10} - 5 = 8 - 5 + \frac{7}{10} = 3 + \frac{7}{10} = 3 \frac{7}{10}\).

3. \(12 - \frac{7}{18}\):

\(12 - \frac{7}{18} = 12 - \frac{7}{18} = 12 - 0.38888... \approx 11.6111...\).

4. \(11 - 3 \frac{5}{12}\):

\(11 - 3 \frac{5}{12} = 11 - 3 - \frac{5}{12} = 8 - \frac{5}{12} = 7 \frac{7}{12}\).

5. \(8 \frac{7}{15} - 3 \frac{11}{15}\):

\(8 \frac{7}{15} - 3 \frac{11}{15} = 8 - 3 + \frac{7}{15} - \frac{11}{15} = 5 - \frac{4}{15} = 4 \frac{11}{15}\).

6. \(10 \frac{9}{14} - 3 \frac{9}{14}\):

\(10 \frac{9}{14} - 3 \frac{9}{14} = 10 - 3 + \frac{9}{14} - \frac{9}{14} = 7\).

Таким образом, результаты вычитаний будут следующими: - \(4 \frac{14}{19} - 2 \frac{5}{19} = 2 \frac{9}{19}\) - \(8 \frac{7}{10} - 5 = 3 \frac{7}{10}\) - \(12 - \frac{7}{18} \approx 11.6111...\) - \(11 - 3 \frac{5}{12} = 7 \frac{7}{12}\) - \(8 \frac{7}{15} - 3 \frac{11}{15} = 4 \frac{11}{15}\) - \(10 \frac{9}{14} - 3 \frac{9}{14} = 7\)
