Answer 1

Answer:

Step-by-step explanation:

find LCM for 5, 7 and 11

LCM = 5x 7 x 11 = 385

Then,

2/5 x 77/77 = 154/385

3/7 x 55/55 = 165/385

7/11 x 35/35 = 245/385

Now add these converted fractions,

So,

154/385 + 165/385 + 245/385

= 154 + 165 + 245 / 385 = 564/385

At last, do lowest form

564 6

--------- = --------

385 55

Therefore, option a is right
