Answer 1

Answer:

1. 25/22

2. 1/15

Step-by-step explanation:

1. -4/-11 + 17/22

minus of 4 and 11 will be cancelled then it

will remain 4/11 + 17/22

the L.C.M will be 22

then it will be 8+17/22 =25/22

2. 8/-15 + 6/10

the L.C.M will be 30 as it comes in the table of 15 as well as 10

Solution -

-8/15 + 6/10 = -16+18/30= 2/30=1/15
