A bag of chips is 24 ounces. A serving size is 3/4 ounce. How many servings are in the bag of chips?

marysya [2.9K]

Answer:

The correct answer to the following question will be "32 servings".

Step-by-step explanation:

The given values are,

A bag of chips = 24 ounces

Serving size = 3/4 ounces

Servings = ?

Now,

On dividing "24 ounces" by "3/4 ounce", we get

⇒ $\frac{24}{\frac{3}{4}}$

⇒ $24\times \frac{4}{3}$

⇒ $8\times 4$

⇒ $32$

Thus, the bag of chips contains "32" servings.
