In the Dog House, Part Deux - Captain Zero to the Rescue (Yet Again)

A quick review...

Look familiar? 
Pat scored 54 out of 200 on a test. What percent is this?


The key to solving these types of questions comes in the words " out of ".




The " out of " number needs to be thrown " out of " the house.  200 is not allowed in the house.


54 is inside...


and 200 is out of the house, in the dog house...


So now we have...

200 divided into 54. 

This is a job for Captain Zero. (More powerful than a speeding doughnut, able to leap tall O's in a single bound...)


Looking at the roof line, you will see that 27 is to the right of the decimal. Whatever is to the right of your decimal becomes your %. So...

.27 = 27%
.03 = 3%, etc.
