Question

Many medications are determined by the weight of the patient in kilograms. When a patient’s weight is measured in pounds, the doctor must then convert the weight to kilograms. The table shows conversions for common units of weight.

Answer 1

70.2 kilograms

Explanation:

In order to calculate this you just have to do a rule of three, where you use the equivalence of the pounds by the kilograms, in the table you see that 1 pound equals .45 kilograms, so you use that for your equivalence:

`(1pound)/(.45kilograms)= (156 pounds)/(x)`

`x=(165*.45)/(1 pound)`

`x=70.2 kilos`

So we know that the patient weights 70,2 kilograms.

Answer 2

70.2

Explanation:

Multiply the weight in pounds by the conversion factor.

`156\,lb*(0.45\,kg)/(1\, lb)=70.2\,kg`
