Answer 2

`(-1)/(6)`

Explanation:

`((3)/(10) )((-5)/(9))`

To multiply both fraction , we multiply the numerator with numerator and denominator with denominator

3 times -5 is -15

10 times 9 is 90

`((3)/(10) )((-5)/(9))`

`(-15)/(90)`

Divide top and bottom by 5

`(-3)/(18)`, divide both sides by 3

`(-1)/(6)`
