You need to set the correct porportion. x is the percent value you want to find. 100 is the maximum percentage. 420mg is what was taken out of the maximum 560mg dose.

You will cross multiple.

you will divide 42000 by 560


The complete answer will be: The patient took 75% of the 560mg dose of medication.
