Question

2/3+-4/5+7/15+-11/20​

Answer 1

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)
