Answer 2

Answer: 1.19271 liters

Step-by-step explanation:

Given: The recommended amount of fluid to adult =64 fluid ounces

We know that 1 fluid ounce = 0.0295735 liters

Then, $64\text{ fluid ounces }=64\times0.0295735\\\Rightarrow 64\text{ fluid ounces }=1.89271\ l$

Since, Josey has already consumed 700 milliliters of water.

We know that 1 liter = 1000 ml

1 ml=$\frac{1}{1000}$ l

Thus, 700 ml =0.7 liters

The required amount of liquid he need to drink more = $1.89271-0.7=1.19271$ ml
