FranTo find the number of multiples of 21 between 200 and 400, we first need to find the first multiple of 21 in that range, which is 210. Then, we find the last multiple of 21 in that range, which is 399. To find the number of multiples, we divide the last multiple by 21 and subtract the first multiple by 21, then add 1. So, (399/21) - (210/21) + 1 = 19 - 10 + 1 = 10. Therefore, there are 10 multiples of 21 between 200 and 400.
