Answer 1

1/3-1/6= 3/20+3/4= 7/9-2/3= 1/4+1/5= 2/5+4/15= 1/3+1/4= 2/3-2/5= 1/5-1/6= 1/2+1/4= 7/6-1= 1/2+2/7= 1/2-1/3= 3/4+1/8 5/6-7/12= 2/5+3/10=1

Answer 2

Давайте по очереди решим каждое из данных уравнений:

1. $\frac{1}{3} - \frac{1}{6} = \frac{2}{6} - \frac{1}{6} = \frac{1}{6}$
2. $\frac{3}{20} + \frac{3}{4} = \frac{3}{20} + \frac{15}{20} = \frac{18}{20} = \frac{9}{10}$
3. $\frac{7}{9} - \frac{2}{3} = \frac{7}{9} - \frac{6}{9} = \frac{1}{9}$
4. $\frac{1}{4} + \frac{1}{5} = \frac{5}{20} + \frac{4}{20} = \frac{9}{20}$
5. $\frac{2}{5} + \frac{4}{15} = \frac{6}{15} + \frac{4}{15} = \frac{10}{15} = \frac{2}{3}$
6. $\frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}$
7. $\frac{2}{3} - \frac{2}{5} = \frac{10}{15} - \frac{6}{15} = \frac{4}{15}$
8. $\frac{1}{5} - \frac{1}{6} = \frac{6}{30} - \frac{5}{30} = \frac{1}{30}$
9. $\frac{1}{2} + \frac{1}{4} = \frac{2}{4} + \frac{1}{4} = \frac{3}{4}$
10. $\frac{7}{6} - 1 = \frac{7}{6} - \frac{6}{6} = \frac{1}{6}$
