How do you solve #\frac { k } { - 9 } = - \frac { 1 } { 3 }#?

Answer 1

Eva Abramson

#k=3#

Cross multiply as described below:

#k/-9= -1/3#

#k xx 3 = -1 xx (-9)#

#3k = 9#

#k = 9/3#

#k=3#

Checking the answer:

#3/-9 = -1/3#---> Correct!

To solve the equation (\frac{k}{-9} = -\frac{1}{3}), you need to isolate (k).

First, multiply both sides of the equation by (-9) to eliminate the fraction:

(\frac{k}{-9} \times -9 = -\frac{1}{3} \times -9)

This simplifies to (k = 3).

So, the solution to the equation is (k = 3).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
