Answer 1

1. 1 6/35
2. 2 7/8
3. 1/24
4. 4 11/35

Answer 2

1. To add $\frac {3}{5}$ and $\frac {4}{7}$, we need to find a common denominator. The least common multiple of 5 and 7 is 35. Therefore, we can rewrite the fractions as $\frac {21}{35}$ and $\frac {20}{35}$. Adding these together gives $\frac {41}{35}$, which is equivalent to 1 6/35.
2. To add $1\frac {3}{8}$ and $1\frac {1}{2}$, we first add the whole numbers together, which gives 2. Next, we add the fractions $\frac {3}{8}$ and $\frac {1}{2}$. To do this, we need a common denominator. The least common multiple of 8 and 2 is 8. Therefore, we can rewrite the fractions as $\frac {3}{8}$ and $\frac {4}{8}$. Adding these together gives $\frac {7}{8}$.
3. To subtract $\frac {7}{8}$ from $\frac {11}{12}$, we need a common denominator. The least common multiple of 8 and 12 is 24. Therefore, we can rewrite the fractions as $\frac {22}{24}$ and $\frac {21}{24}$. Subtracting these gives $\frac {1}{24}$.
4. To subtract $2\frac {2}{5}$ from $6\frac {5}{7}$, we first subtract the whole numbers, which gives 4. Next, we subtract the fractions $\frac {5}{7}$ and $\frac {2}{5}$. To do this, we need a common denominator. The least common multiple of 7 and 5 is 35. Therefore, we can rewrite the fractions as $\frac {25}{35}$ and $\frac {14}{35}$. Subtracting these gives $\frac {11}{35}$.
