Question

Find the value of k
6/-9 = 2/k = 8/-11

ex. 6
_
-9​

Answer 1

Answer:

6/-9=2/k

6k= -18 ( by cross multiplication)

k = -3

Answer 2

Answer:

6/-9 = 2/k = 8/-11

==> 6/-9 = 2/k

==> 2/-3 = 2/k

==> 2(1/-3) = 2(1/k)

==> 1/-3 = 1/k

==> -3 = k

answer = -3

and 2/k = 8/-11

==> k/2 = -11/8 (reversing both sides)

==> k = -11/8 ×2

==> k = -11/4
