5/9$

Explanation:

Each pound will cost a value so that if the value was multiplied by 18 it will give us 10$ . We don't know the value of the pound so let's call it x.

18x=10$

Divide both sides by 18

(cancel(18)x)/cancel18=(10$)/18

x=10/18$

10/18$ is our answer

But we can simplify it by dividing both the numerator and the denominator by the highest common factor 2

(10-:2)/(18-:2)=5/9$

Our final answer is 5/9$
