a) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number.

(27)/(45) =
(x)/(5)

Next, you would cross multiply.
135 = 45x

Now, the last step would be to isolate the x. To do this, you would divide both sides by 45.
3 = x


(27)/(45) =
(3)/(5)


b) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number.

(2)/(6) =
(3)/(x)
Next, you would cross multiply.
18 = 2x

Now, the last step would be to isolate the x. To do this, you would divide both sides by 2.
9 = x


(2)/(6) =
(3)/(9)


I hope this helps!
