Thank you for the opportunity to help you with your question!

Hi there.

I am going to explain to you how this is done.

Its very easy you just follow these steps

18/30=x/15

To find the value of x You first multiply both sides with the denominator 15 and you will have the following

18/30*15=x/15*15

on the right hand side the denominator will be cancelled by the 15 we have multiplied and therefore you will get

18/30*15=x

Divide 30 by 15 and you will get

18/2*1=x

Divide 18 by 2 to get 9 and therefore you will have the value of x

9=x

Therefore x=9


Hope this helps you understand that. If you have any question fell free to ask and i will be ready to help.

Thanks
