Answer:
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.
