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
