Si debes tomar 0.035 litros de agua por cada kg de peso al día, si pesaras 50 kg ¿Cuánta agua deberás beber en un día? ayuda porfavor

Answers

Answer:

Deberás beber 1.75 litros de agua en un día.

Step-by-step explanation:

De acuerdo a la información dada, puedes utilizar una regla de tres para encontrar la cantidad de agua que deberás beber en un día si pesas 50 kg dado que debes tomar 0.035 litros por cada kg:

 1kg     →     0.035 litros

50 kg  →              x

x=(50*0.035)/1=1.75 litros

De acuerdo a esto, la respuesta es que deberás beber 1.75 litros de agua en un día.
