Divide Whole Numbers in Applications
We will use the same strategy we used in previous sections to solve applications. First, we determine what we are looking for. Then we write a phrase that gives the information to find it. We then translate the phrase into math notation and simplify it to get the answer. Finally, we write a sentence to answer the question.
Example
Cecelia bought a \(\text{160-ounce}\) box of oatmeal at the big box store. She wants to divide the \(160\) ounces of oatmeal into \(\text{8-ounce}\) servings. She will put each serving into a plastic bag so she can take one bag to work each day. How many servings will she get from the big box?
Solution
We are asked to find the how many servings she will get from the big box.
| Write a phrase. | 160 ounces divided by 8 ounces |
| Translate to math notation. | \(160÷8\) |
| Simplify by dividing. | \(20\) |
| Write a sentence to answer the question. | Cecelia will get 20 servings from the big box. |
