10. What is the result of adding 3/5 and 2/7?

To add fractions with different denominators, we need to find a common denominator.

Common denominator of 5 and 7 is 35.

Convert 3/5 and 2/7 to have 35 as the denominator:

\[ \frac{3}{5} \times \frac{7}{7} = \frac{21}{35} \]

\[ \frac{2}{7} \times \frac{5}{5} = \frac{10}{35} \]

Now, add the fractions:

\[ \frac{21}{35} + \frac{10}{35} = \frac{31}{35} \]

So, the correct answer is:

b) 31/35
