3) Вычислик а) 5/96 + 4/96 - 5/96 б) 5/18 - 4/18 + 4/18 в) 44/96 - 33/96 + 5/96 б) 4/54 + 6/54 - 5/54 ч) 13/52 + 8/52 + 5/52 д) 12/52 - 9/52 + 5/52

Вычислим:

1. $$ \frac{5}{96}+\frac{4}{96}-\frac{5}{96} = \frac{5+4-5}{96}=\frac{4}{96} $$

   Сократим дробь на 4:

   $$ \frac{4}{96} = \frac{4:4}{96:4} = \frac{1}{24} $$

2. $$ \frac{5}{18}-\frac{4}{18}+\frac{4}{18} = \frac{5-4+4}{18} = \frac{5}{18} $$

3. $$ \frac{44}{96}-\frac{33}{96}+\frac{5}{96} = \frac{44-33+5}{96}=\frac{16}{96} $$

   Сократим дробь на 16:

   $$ \frac{16}{96} = \frac{16:16}{96:16}=\frac{1}{6} $$

4. $$ \frac{4}{54}+\frac{6}{54}-\frac{5}{54} = \frac{4+6-5}{54} = \frac{5}{54} $$

5. $$ \frac{13}{52}+\frac{8}{52}+\frac{5}{52} = \frac{13+8+5}{52} = \frac{26}{52} $$

   Сократим дробь на 26:

   $$ \frac{26}{52} = \frac{26:26}{52:26}=\frac{1}{2} $$

6. $$ \frac{12}{52}-\frac{9}{52}+\frac{5}{52} = \frac{12-9+5}{52} = \frac{8}{52} $$

   Сократим дробь на 4:

   $$ \frac{8}{52} = \frac{8:4}{52:4} = \frac{2}{13} $$
