Answer:
1.
[tex] \frac{3}{4} + \frac{2}{5} = \frac{23}{20} [/tex]
2.
[tex] \frac{13}{7} + \frac{3}{2} = \frac{47}{14} [/tex]
3.
[tex] \frac{4}{5} + \frac{9}{7} = \frac{73}{35} [/tex]
4.
[tex] \frac{3}{2} + \frac{4}{3} = \frac{17}{6} [/tex]
5.
[tex] \frac{5}{7} + \frac{1}{4} = \frac{27}{28} [/tex]
6.
[tex] \frac{5}{2} - \frac{2}{7} = \frac{31}{14} [/tex]
7.
[tex] \frac{4}{3} - \frac{1}{2 } = \frac{5}{6} [/tex]
8.
[tex] \frac{5}{7 } - \frac{1}{2} = \frac{3}{14} [/tex]
9.
[tex] \frac{8}{5} - \frac{5}{10} = \frac{11}{10} [/tex]
10.
[tex] \frac{12}{5} - \frac{7}{7} = \frac{7}{5} [/tex]
Oh Yan na!
Tama po yan!
