Fill in the boxes so that the fractions so formed are improper fractions:
`7/(square), 7/(square), 7/(square)`

Answer

To solve the problem of filling in the boxes so that the fractions formed are improper fractions, we need to understand what an improper fraction is. An improper fraction is one where the numerator is greater than or equal to the denominator.

### Step-by-Step Solution:

1. **Identify the Numerator**:
The numerator given is 7.

2. **Understand the Condition for Improper Fractions**:
For a fraction to be improper, the numerator (which is 7) must be greater than or equal to the denominator. This means the denominator must be less than or equal to 7.

3. **Determine Possible Values for the Denominator**:
The possible values for the denominator (the box) can be any number that is less than or equal to 7. Therefore, the possible values for the box can be:
- 1
- 2
- 3
- 4
- 5
- 6
- 7

4. **Fill in the Boxes**:
We can fill the boxes with any of the values listed above. For example:
- 7/1
- 7/2
- 7/3
- 7/4
- 7/5
- 7/6
- 7/7

Any of these combinations will result in an improper fraction.

### Final Answer:
The boxes can be filled with any of the following values to form improper fractions:
- 1, 2, 3, 4, 5, 6, or 7.
