Answer:

1) 9/8

$\frac{5}{15} + \frac{5}{9} = \frac{15}{45} + \frac{25}{45} = \frac{40}{45} \div 5 = \frac{8}{9}$

2) 3

$\frac{3}{9} \times \frac{7}{ 7} = \frac{21}{64} \times \frac{64}{64} = \frac{3}{1} \times \frac{1}{1} = \frac{3}{1} or3$

3) 2 1/5

$2 \frac{3}{6} \times \frac{2}{5} = 2 \frac{15}{30} \times \frac{12}{30} = 2 \frac{3}{5} \times \frac{2}{6} \\ = 2 \frac{6}{30} \div 6 = 2 \frac{1}{5}$
