Solve by associative property

Answer 1

Answer:

3/19

Step-by-step explanation:

first of all you have to add those values which are not in the bracket which are 7/38 and 9/19

when you will add them you will get 25/38

now you have to solve the bracket

-1/2+25/38

so you will get 3/19

Answer 2

Answer:

(-1/2)+7/38+9/19

a+(b+c)

(-1/2)+(7/38+9/19)

(-1/2)+(7/38+18/38)

(-1/2)+(25/38)

(-1/2)+25/38

-19/38+25/38

-19+25/38

6/38

3/19
