EXERCISE 2.1

Solve: $\frac{3}{5}+\frac{2}{7}$

Solve: $\frac{9}{11}-\frac{4}{15}$

If the value of $\frac{7}{10}+\frac{2}{5}+\frac{3}{2}$ is $k\frac{3}{5}$, find the value of $k$

If the value of $2\frac{2}{3}+3\frac{1}{2}$ is $a\frac{1}{a}$, then find the value of $a$

Solve and write the answer in improper fraction form: $8\frac{1}{2}-3\frac{5}{8}$

Which of the following is the smallest: $\frac{2}{9}, \frac{2}{3}, \frac{8}{21}$.

Which of the following is the smallest: $\frac{1}{5}, \frac{3}{7}, \frac{7}{10}$

Salil wants to put a picture in a frame. The picture is $7\frac{3}{5} \mathrm{cm}$ wide. To fit in the frame the picture cannot be more than $7\frac{3}{10} \mathrm{cm}$  wide. If the picture is to be trimmed by $\frac{p}{q} \mathrm{cm},$ then find the value of $\frac{p}{q}$.
