Final answer:
The correct symbol to place between the numbers 46 and 51 is > (greater than).
Step-by-step explanation:
The correct symbol to place between the numbers 46 and 51 is > (greater than). This is because 51 is greater than 46.
To determine the correct symbol to use, we compare the two numbers and determine their relationship. Since 51 is larger than 46, we use the greater than symbol to show that 51 is greater than 46.
