Answer:
116 mg
Step-by-step explanation:
From the statement we have that a patient receives 1 1/3 mg of medicine per kilogram of his weight.
The first thing is to pass the mixed number 1 1/3 to a rational number, like this:
1 + 1/3 = 1.33
So it would be 1.33 mg of medicine per kg, if the patient weighs 87 kg, he should be given a total of:
1.33 * 87 = 116
A total of 116 mg should be given to that patient.
