Answer:
-7/20
Step-by-step explanation:
2/3 +(-4/5)+7/15+(-11/20)
Take the LCM of (3,5,15,20) =60
so,
2/3×20/20=40/60
-4/5×12/12=(-48/60)
7/15×4/4=28/60
-11/20×3/3=(-33/60)
Then,
(46/60)+(-48/60)+(28/60)+(-33/60)
If we ignore the denominator so it will be
much easy to solve
So,
46-48+28-33=74-81=(-7)
Answer is (-7/20)
