Question

a patient was supposed to take 560 mg of medicine but took on The 420 mg what percent of medicine does she take

Answer 1

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.


`(x)/(100) * (420)/(560)`

You will cross multiple.


`560x = 42000`

you will divide 42000 by 560


`(560x)/(560) = (42000)/(560)`

`x = 75`

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