Answer 2

To solve this proportion, we can cross-multiply.

The proportion is:

3/5 : (-2/5) : (-5/9)

Cross-multiplying, we have:

(3/5) * (-5/9) = (-2/5) * x

Simplifying, we get:

-15/45 = -2x/5

To solve for x, we can cross-multiply again:

-15 * 5 = -2x * 45

-75 = -90x

Dividing both sides by -90, we have:

x = -75 / -90

Simplifying further, we get:

x = 5/6

Therefore, the value of x in the proportion 3/5 : (-2/5) : (-5/9) is 5/6.
