Answer:
1.2 litres more water should Josie drink.
Step-by-step explanation:
As given
It is recommended that an adult drink 64 fluid ounces of water everyday .
As given
1 ounce = 0.0296 litre .
Now convert 64 ounces into litre.
64 ounce = 64 × 0.0296
= 1.9 litres (Approx)
As
1 litre = 1000 ml
Now convert 700 ml into litre.
700 ml = 0 .7 litre
Thus
Recommended amount of water a adult should drink = Amount of water Josie already consumed + More water should Josie drink.
Putting the value
1.9 litres = 0 .7 litres + More water should Josie drink.
More water should Josie drink = 1.9 - 0.7
More water should Josie drink = 1.2 litres .
Therefore 1.2 litres more water should Josie drink.
