Answer 1

45

Explanation:

-2/9 x 18/5 + 4/5 = 45

hope I'm right

Answer 2

0

Explanation:

Reciprocal of -9/2 = -2/9

Reciprocal of 5/18 = 18/5

Multiplying both:

=>
`(-2)/(9)*(18)/(5)`

=>
`(-2*2)/(5)`

=> -4/5

Additive Inverse of -4/5 = 4/5

So, Adding both of them:

=>
`-(4)/(5) + (4)/(5)`

=> 0
