In each of the following pairs of numbers, state which whole number is on the left of the other number on the number line. Also write them with the appropriate sign `(gt, lt)` between them.
370, 307

Answer

To solve the problem, we need to determine the position of the numbers 370 and 307 on a number line and compare them.

### Step-by-Step Solution:

1. **Identify the Numbers**: We have two numbers: 370 and 307.

2. **Understand the Number Line**: On a number line, numbers increase in value as you move from left to right. This means that smaller numbers are located to the left of larger numbers.

3. **Compare the Numbers**:
- We need to see which number is smaller.
- Clearly, 307 is less than 370 because 307 comes before 370 when counting.

4. **Determine Their Positions**:
- On the number line, 307 is to the left of 370.
- Therefore, we can say that 307 is on the left of 370.

5. **Write the Comparison**:
- Since 307 is smaller than 370, we can write this relationship using the appropriate sign:
- 307 < 370.

### Final Answer:
307 is on the left of 370 on the number line, and we can write it as:
307 < 370.
