Let's solve the given problem step by step.

### Given Information:
- Total number of people in the museum: **250**
- **\(\frac{2}{5}\)** of the 250 people are **girls**.
- **\(\frac{3}{10}\)** of the 250 people are **boys**.
- The rest of the people are **adults**.

### Steps to Solve:

1. **Calculate the Number of Girls:**
   - The fraction of people who are girls is \(\frac{2}{5}\).
   - Number of girls = \(\frac{2}{5} \times 250 = 100\).

2. **Calculate the Number of Boys:**
   - The fraction of people who are boys is \(\frac{3}{10}\).
   - Number of boys = \(\frac{3}{10} \times 250 = 75\).

3. **Calculate the Number of Adults:**
   - Total number of people = 250.
   - Number of children (girls and boys) = \(100 + 75 = 175\).
   - Number of adults = \(250 - 175 = 75\).

### Answer:
The number of **adults** in the museum is **75**.

5. If \( \frac{1}{4} \) of the adults left the museum, how many adults would remain?

### Tip:
When solving problems involving fractions, it's often helpful to simplify the fractions first or directly multiply to keep track of each group clearly.

There are 250 people in a museum. 2/5 of the 250 people are girls. 3/10 of the 250 people are boys. The rest of the 250 people are adults. Work out the number of adults in the museum.
