Question

a home health care assistant prepares 10 and a half ounces of formula the mixture is 1/3 formula and 2/3 water how much formula does she need to make 10 and 1/2 oz mixture how much water does she need to make 10 and a half ounce of mixture

Answer 1

Total amount of the mixture = $10\frac{1}{2}=10.5$ ounces

Proportion of formula = $\frac{1}{3}$

Proportion of water = $\frac{2}{3}$

Amount of water needed to make the mixture can be given as:

Total amount of mixture x Proportion of water

Using the values, we get:

Amount of water needed = $10.5*\frac{2}{3}$ = 7 ounces

Similarly the amount of formula needed will be:

Total amount of mixture x Proportion of formula

Using the values, we get:

Amount of formula needed = $10.5*\frac{1}{3}$ = 3.5 ounces

Therefore, the home health care assistant needs 3.5 ounces of formula and 7 ounces of water to prepare 10 and a half ounces of formula.
