For question 8:
To find how many mg of medicine the patient should receive, you need to multiply the weight of the patient (87 kg) by the dosage per kg (1 1/3 mg).
First, convert the mixed number 1 1/3 to an improper fraction.
1 1/3 = (3*1 + 1)/3 = 4/3
Now multiply the weight by the dosage per kg:
87 kg * 4/3 mg/kg = (87 * 4)/(3) mg = 348/3 mg
Divide the numerator (348) by the denominator (3) to simplify the fraction:
348/3 = 116
Therefore, the patient should receive 116 mg of medicine.
