$\sf \frac{3}{7} + \frac{4}{5} \\ \\ \sf lcm \: of \: 7 \: and \: 5 \: = 35 \\ \\ \sf \: \frac{5 \times 3 + 4 \times 7}{35} = \frac{15 + 28}{35} \\ \\ \sf = \frac{43}{35}$

Answer 2

Step-by-step explanation:

3 / 7 + 4 / 5

LCM = 35

3 / 7 × 5 / 5 = 15 / 35

4 / 5 × 7 / 7 = 28 / 35

15 / 35 + 28 / 35 = 15 + 28 / 35

= 43 / 35
