It is recommended that an adult drink 64 fluid ounces of water every day. Josey has already consumed 700 millitiers of water. How many more liters should he drink today?

33.814 fluid ounces = 1 liter

64 ounces = 64/33.814 liters = 1.89 liters is what she needs daily

1000 milliliters = 1 liter

700 milliliters = 0.7 liters is what she already drank

1.89-0.7 = 1.19 liters she still needs to drink

In the given question it is already mentioned that an adult drinks 54 fluid ounces of water daily. Also it is mentioned that Josey has already drank 700 milliliters of water.

Now fopr solving this problem we have to fist convert 64 ounces to liter and then convert 700 milliliter to liter and then only can we get the answer to the question.

We already know

1 ounce = 0.29 liter

64 ounce = 64 * 0.29 liter

= 18.56 liter

So 18.56 liter is the daily recommendation for an adult to drink water

Again

1 milliliter = 0.001 liter

700 ml = 0.001 * 700 liter

= 0.7 liter

So Josey has already drank 0.7 liters of water

Amount of water Josey still needs to drink = (18.56 - 0.7) liter

= 17.86 liter
