Use the appropriate symbol `=,lt` or `gt` to fill the following blanks : `-3…7`

Answer

To solve the problem of filling in the blank between -3 and 7 with the appropriate symbol, we can follow these steps:

### Step 1: Understand the values
We have two numbers to compare: -3 and 7.

### Step 2: Identify the nature of the numbers
- -3 is a negative integer.
- 7 is a positive integer.

### Step 3: Compare the numbers
In the number line, negative numbers are always less than positive numbers. Therefore, -3 is less than 7.

### Step 4: Choose the appropriate symbol
Since -3 is less than 7, we will use the symbol `<` (less than) to fill in the blank.

### Final Statement
-3 < 7
