The problem is asking for two different ways to determine how many 1/4-cup scoops of walnuts are needed to prepare two dishes: banana-walnut oatmeal, requiring 3/8 cup of walnuts, and spinach-walnut salad, requiring 3/4 cup. Here's a step-by-step breakdown and two methods to find the answer.

### Total Walnut Requirement:
You need \( \frac{3}{8} \) cups for the oatmeal and \( \frac{3}{4} \) cups for the salad. To add these:
\[
\frac{3}{4} + \frac{3}{8}
\]
To add fractions, find a common denominator. The least common denominator between 4 and 8 is 8, so:
\[
\frac{3}{4} = \frac{6}{8}
\]
Now, add:
\[
\frac{6}{8} + \frac{3}{8} = \frac{9}{8}
\]
So, the total amount of walnuts needed is \( \frac{9}{8} \) cups.

### Method 1: Division by 1/4-Cup Scoops
Since you have a 1/4-cup scoop, divide the total walnut requirement by 1/4:
\[
\frac{\frac{9}{8}}{\frac{1}{4}} = \frac{9}{8} \times \frac{4}{1} = \frac{36}{8} = 4.5 \text{ scoops}
\]
You need 4.5 scoops of walnuts.

### Method 2: Breaking into Two Steps
1. **For the oatmeal**: You need \( \frac{3}{8} \) cups. How many 1/4-cup scoops is this?
   \[
   \frac{\frac{3}{8}}{\frac{1}{4}} = \frac{3}{8} \times \frac{4}{1} = \frac{12}{8} = 1.5 \text{ scoops}
   \]

2. **For the salad**: You need \( \frac{3}{4} \) cups. How many 1/4-cup scoops is this?
   \[
   \frac{\frac{3}{4}}{\frac{1}{4}} = \frac{3}{4} \times \frac{4}{1} = 3 \text{ scoops}
   \]

Now, add the number of scoops from each part:
\[
1.5 + 3 = 4.5 \text{ scoops}
\]

Thus, in both methods, you find that you need 4.5 scoops of walnuts.

Here are five related questions:
1. How do you multiply and divide fractions?
2. How do you find a common denominator when adding fractions?
3. What is the significance of using common denominators in fraction operations?
4. How would the answer change if the scoop size was different (e.g., 1/3 cup)?
5. How could you estimate the number of scoops without exact fraction operations?

**Tip**: When dividing by a fraction, remember that dividing is equivalent to multiplying by the reciprocal of the fraction.

You are measuring walnuts for banana-walnut oatmeal and a spinach and walnut salad. You need 3/8 cup of walnuts for the oatmeal and 3/4 cup of walnuts for the salad. You have a 1/4-cup scoop. Describe two different ways to find how many scoops of walnuts you will need.
