Answer 1

Answer:

I didn't understand whether the sign (-) is for 2 or not so i will solve both ways

Step-by-step explanation:

a)-2/5 + (-3/7)

-2/5 -3/7

-2*7/5*7 - 3*5/7*5- lcm is 35

-14/35-15/35

-29/35

b) 2/5+(-3/7)

2/5-3/7

2*7/5*7-3*5/7*5

14/35-15/35

14-15/35

-1/35

$\frac{ - 2}{5} + \frac{ - 3}{7} \\ \\ \frac{ - 14 + ( - 15)}{35} \\ \\ \frac{ - 14 - 15}{35} \\ \\ \frac{ - 29}{35}$
