Answer 1

$3 \frac{3}{10} - 1 \frac{7}{15} = 3 \frac{9}{30} - 1 \frac{14}{30} = 2 \frac{39}{30} - 1 \frac{14}{30} = 1 \frac{25}{30} = 1 \frac{5}{6}$

$8 \frac{7}{8} - 4 \frac{5}{6} = 8 \frac{21}{24} - 4 \frac{20}{24} = 4 \frac{1}{24}$

$5 \frac{5}{12} - 3 \frac{3}{8} = 5 \frac{10}{24} - 3 \frac{9}{24} = 2 \frac{1}{24}$

$3 \frac{4}{15} - 1 \frac{1}{6} = 3 \frac{8}{30} - 1 \frac{5}{30} = 2 \frac{3}{30} = 2 \frac{1}{10}$

Answer 2

3 3/10 - 1 7/15 = 3 9/30 - 1 14/30 = 2 39/30 - 1 14/30 = 1 25/30 = 1 5/6

8 7/8 - 4 5/6 = 8 21/24 - 4 20/24 = 4 1/24

5 5/12 - 3 3/8 = 5 10/24 - 3 9/24 = 2 1/24

3 4/15 - 1 1/6 = 3 8/30 - 1 5/30 = 2 3/30 = 2 1/10
