Answer 1

1)

$3 \frac{1}{15} + 2 \frac{7}{25} = 3 \frac{5}{75} + 2 \frac{21}{75} = 5 \frac{26}{75}$

2)

$2 \frac{7}{10} + 9 \frac{2}{15} = 2 \frac{21}{30} + 9 \frac{4}{30} = 11 \frac{25}{30} = 11 \frac{5}{6}$

3)

$9 \frac{5}{18} + 6 \frac{1}{12} = 9 \frac{10}{36} + 6 \frac{3}{36} = 15 \frac{13}{36}$

4)

$1 \frac{7}{12} + 3 \frac{5}{9} = 1 \frac{21}{36} + 3 \frac{20}{36} = 4 \frac{41}{36} = 5 \frac{5}{36}$

5)

$5 \frac{5}{24} + 2 \frac{1}{6} = 5 \frac{5}{24} + 2 \frac{4}{24} = 7 \frac{9}{24} = 7 \frac{3}{8}$

6)

$3 \frac{1}{12} + 4 \frac{2}{15} = 3 \frac{5}{60} + 4 \frac{8}{60} = 7 \frac{13}{60}$
