Answer 2

Answer:

Make the denominators same

LCM of 5,15,20 is 60

$\frac{ - 4}{5} \times \frac{12}{12} = \frac{ - 48}{60} \\ \\ \frac{ - 3}{15} \times \frac{4}{4} = \frac{ - 12}{60} \\ \\ \frac{7}{20} \times \frac{3}{3} = \frac{21}{60}$

Now add them

-48/60-12/60+21/60

=-60/60+21/60

=-39/60

=-13/20
