Find the ratio of:
No. of days in a week to No. of days in a year

Answer

To find the ratio of the number of days in a week to the number of days in a year, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of days in a week**:
- There are 7 days in a week.
- So, we can write:
\[ \text{Days in a week} = 7 \]

2. **Identify the number of days in a year**:
- Typically, there are 365 days in a year.
- Therefore, we can write:
\[ \text{Days in a year} = 365 \]

3. **Set up the ratio**:
- The ratio of the number of days in a week to the number of days in a year can be expressed as:
\[ \text{Ratio} = \frac{\text{Days in a week}}{\text{Days in a year}} = \frac{7}{365} \]

4. **Simplify the ratio**:
- In this case, the ratio \( \frac{7}{365} \) is already in its simplest form since 7 and 365 have no common factors other than 1.
- Thus, we can express the ratio as:
\[ 7 : 365 \]

5. **Conclusion**:
- The required ratio of the number of days in a week to the number of days in a year is:
\[ \text{Final Ratio} = 7 : 365 \]
