a patient was supposed to take 560 mg of medicine but took on The 420 mg what percent of medicine does she take
Sav [38]
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.

\frac{x}{100} \times \frac{420}{560}

You will cross multiple.

560x = 42000

you will divide 42000 by 560

\frac{560x}{560} = \frac{42000}{560}
x = 75

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