To find the number of integers between 400 and 800 that are divisible by 13, we first need to find the smallest and largest multiples of 13 within this range. The smallest multiple of 13 greater than or equal to 400 is 403, and the largest multiple less than or equal to 800 is 793. To find the count of numbers divisible by 13 in this range, we calculate (793-403)/13 + 1 = 31. Therefore, there are 31 numbers between 400 and 800 that are divisible by 13.
