#### Explanation:

Solving implies we determine the value of

In order to solve this, an easy way is to "cross-multiply".

If we were to apply this to our equation...

#19/x=38/100#

#19(100)=38x#

#1900=38x#

#50=x#

We can check our work by subbing in

#19/x=38/100#

#19/50=38/100#

If we simplify the right side of the equal sign.

#19/50=19/50#

They equal each other! This proves that
