Answer 1

$\frac{28}{70} + \frac{36}{90} + \frac{1}{3} \\ = \frac{14}{35} + \frac{18}{45} + \frac{1}{3} \\ = \frac{14}{35} + \frac{2}{5} + \frac{1}{3} \\ = \frac{14}{35} + \frac{14}{35} + \frac{1}{3} \\ = \frac{28}{35} + \frac{1}{3} \\ = \frac{84}{105} + \frac{35}{105} \\ = \frac{119}{105} = \frac{17}{15}$
