Answer 1

option D

Explanation:

`18 (1)/(5) -(-22(2)/(5)) -(-40(1)/(5))`

To get equivalent expression we need to remove the parenthesis

multiply negative sign inside the parenthesis

when we multiply negative and negative it becomes positive.

So the expression becomes

`18 (1)/(5) + 22(2)/(5)+40(1)/(5)`

So, option D is the equivalent expression
