Step-by-step solving: Addition & Subtraction of Fractions
1. [tex]\frac{2}{9} + \frac{3}{9} = \frac{5}{9}[/tex]
2. [tex]\frac{7}{9} - \frac{1}{9} = \frac{6}{9}[/tex]
[tex]\frac{6}9} = \frac{2}{3}[/tex]
3. [tex]\frac{5}{11} + \frac{4}{11} = \frac{9}{11}[/tex]
4. [tex]\frac{16}{24} -\frac{6}{12} = \frac{16}{24} - \frac{12}{24}[/tex]
[tex]\frac{16}{24} - \frac{12}{24} = \frac{4}{24}[/tex]
[tex]\frac{4}{24} = \frac{1}{6}[/tex]
5. [tex]\frac{7}{20} + \frac{3}{8} = \frac{14}{40} + \frac{15}{40}[/tex]
[tex]\frac{14}{40} + \frac{15}{40} = \frac{29}{40}[/tex]
6. [tex]\frac{4}{9} - \frac{1}{4} = \frac{16}{36} - \frac{9}{36}[/tex]
[tex]\frac{16}{36} - \frac{9}{36} = \frac{7}{36}[/tex]
7. [tex]\frac{2}{5} + \frac{7}{10} = \frac{4}{10} + \frac{7}{10}[/tex]
[tex]\frac{4}{10} + \frac{7}{10} = \frac{11}{10}[/tex]
[tex]\frac{11}{10} = 1\frac{1}{10}[/tex]
8. [tex]2+\frac{5}{12} - \frac{1}{3} = 2+\frac{5}{12} - \frac{4}{12}[/tex]
[tex]2+\frac{5}{12} - \frac{4}{12} = 2\frac{1}{12}[/tex]
9. [tex]8 + \frac{1}{4} + \frac{2}{7} = 8 + \frac{7}{28} + \frac{8}{28}[/tex]
[tex]8 + \frac{7}{28} + \frac{8}{28} = 8\frac{15}{28}[/tex]
10. [tex]9\frac{5}{7} - 3\frac{2}{7} = 6\frac{3}{7}[/tex]
