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

1.3 L more.

Step-by-step explanation:

Givens

8 fluid ounces = 1 cup.

240 mL = 1 cup

Solution

4 cups = 1 L

64 fluid ounces = x cups

8/64 = 1 / x Cross multiply

8x = 64 Divide by 8

8x/8 = 64/8

x = 8 cups

So we should be drinking 8 cups a day

1 L = 4 cups

x = 8 cups Cross multiply

4x = 8 cups Divide by 4

x = 8/4

x = 2 Liters.

1 L = 1000 mL

x L = 700 mL

700 * 1 = 1000 * x

Divide by 1000

x = 700 / 1000

x = 0.7 L

He needs to drink 2 L - 0.7L

1.3 more liters.
