Calculate the fluid intake in milliliters for the following meal. assume a glass holds 8oz 1/3 glass of orange juice 1/2 pt milk 1 tuna sandwich 1 popsicle

405 ml.
   For a fluid restriction diet, all substances that are liquid at room temperature are restricted. For the 4 items listed in the meal, that would be the orange juice, milk, and popsicle. So let's calculate that. First, let's do the orange juice and milk:
 1/3 * 8 oz = 8/3 oz
 1/2 pt * 16 oz/pt = 8 oz
 8/3 + 8 = 8/3 + 24/3 = 32/3 = 10.66667 oz

   Now let's convert the values into ml.
 10.66667 oz * 29.5735 ml/oz = 315.4506667 ml

   Now the reason for not adding the popsicle earlier is because 1 popsicle is 90 ml. So add that in.
 315.4506667 ml + 90 ml = 405.4506667 ml
   Rounding to the nearest ml gives you 405 ml.

The additive identity is 0 because when you add 0 to a number, you get the identical number as an answer.a + 0 = a
