Answer 1

Answer:

$\frac{13}{35} ans$

Step-by-step explanation:

$\frac{ - 3}{7} + \frac{4}{5} = \frac{ - 15 + 28}{35} = \frac{13}{35} \: ans$

Answer 2

Answer:

$= + \times + = + \\ = - \times - = + \\ = - \times + = - \\ = + \times - = -$

$\red \: = \frac{ - 3}{7} + \frac{4}{5} \\ = find \: the \: lcm \: of \: the \: \\ denominators \: \\ = lcm = 35 \\ = \frac{ - 3 \times + 5}{7 \times 5} = \frac{ - 15}{ + 35} \\ = \frac{4 \times 7}{5 \times 7} = \frac{ + 28}{ + 35} \\ = \frac{ - 15}{ + 35} + \frac{ + 28}{ + 35} \\ = \frac{ - 15 + ( + 28)}{35} \\ = \frac{ - 15 + 28}{35} \\ = \frac{ - 43}{35} = answer$
