You weigh a gallon of 2% milk in science class and learn that is approximately 8.4 pounds. You pass the milk to the next group, and then realize that your teacher wanted an answer in kilogram, not pounds. Explain how you can adjust your answer without weighing the milk again. Then give the weight in kilograms.

Respuesta :

1 pound is 0.453592 kilograms
so 8.4 pounds is 3.81018 kilograms
You would cross multiply and make sure the units are lined up with each other

1[tex] \frac{1 lb}{0.453592 kg} = \frac{8.4 lb}{x} [/tex]
then you would cross multiply and get 3.81018
Conversions
1 lb= 2.2 kg
8.4 lb×2.2= 18.48 kg
