Which of the following is a rational number between 5 and 514?

One rational number between 5 and 514 is 100.

To find a rational number between 5 and 514, we need to consider numbers that can be expressed as a fraction.

One approach is to find the midpoint between 5 and 514, and check if it is a rational number.

To find the midpoint:
Step 1: Add the two numbers together: 5 + 514 = 519.
Step 2: Divide the sum by 2: 519 ÷ 2 = 259.5.

Since 259.5 is not a whole number, it is not a rational number.

To find a rational number, we can look for a fraction between 5 and 514.

For example, let's try 6.

6 is between 5 and 514, so it is a valid option.

Therefore, one rational number between 5 and 514 is 6.
