Answer:
49mg
Step-by-step explanation:
let's call every 7 mg of fever reducer a "dose"
Divide the weight of Greg by the weight per "dose"
42/6 = 7 doses
Each "dose" is 7mg. Multiply the number of doses by 7mg.
7 dose X 7mg = 49mg
Therefore, if Greg weighs 42kg, the pediatrician will prescribe 49mg of fever reducer.
Answer: 49 mg
Step-by-step explanation:
Hi, to answer this we have to use proportions.
Proportion = weight/ mg of fever reducer
For every 6 kg of a child's weight, pediatricians prescribe 7 mg of fever reducer: 6/7
For 42 kg: 42/x
Where x is the amount in mg of fever reducer for Greg.
6 /7 = 42/x
Solving for x
x = 42/ (6/7)
x= 49
