Answer 2

Step-by-step explanation:

1) 11/17 + 13/19

Equalize the denominators by taking their LCM

LCM of 17 and 19=323

11*19/17*19 + 13*17/19*17

209/323 + 221/323

430/323

Now if you want it in decimals then it'll be

1.33

2) firstly we will convert them. We will get

25/11 + 80/77

Now equalize the denominators by taking their LCM.

LCM of 11 and 77 = 77

25*7/11*7 + 80*1/77*1

175/77 + 80/77

255/77

Now if you want it in decimals then it'll be

3.31

Hope it helped you
