When we are including both the first number and the last number, we must add 1 to their difference. Thus, the number of integers between 51 and 107, inclusive, is 107 - 51 + 1 = 57.lheiannie07 wrote:How many integers are there between 51 and 107, inclusive?

Let's take a look at your question.
To find the number of integers between any two given integers, inclusive, we use the formula:
Highest Number - Lowest Number + 1
= 107 - 51 + 1
= 57
Therefore, Option D is correct.
Hope it helps.
