Answer 1

k=-27.78

Explanation:

just do -15 divided by .54 and isolate k

Answer 2

`\large\boxed{k=-(250)/(9)\to k=-27(7)/(9)}`

Explanation:

`0.54k=-15\qquad\text{multiply both sides by 100}\\\\(100)(0.54k)=(100)(-15)\\\\54k=-1500\qquad\text{divide both sides by 54}\\\\(54k)/(54)=(-1500)/(54)\\\\k=-(1500:6)/(54:6)\\\\k=-(250)/(9)`
