To find the numbers between 1 and 100 inclusive that are divisible by either 9 or 4, we first determine how many numbers are divisible by 9 and how many are divisible by 4. There are 11 numbers divisible by 9 (9, 18, 27, ..., 99) and 25 numbers divisible by 4 (4, 8, 12, ..., 100). However, we must be careful not to double-count numbers divisible by both 9 and 4 (36, 72). Therefore, the total number of numbers divisible by 9 or 4 between 1 and 100 inclusive is 11 + 25 - 2 = 34.
To find numbers between 30 and 40 that are divisible by both 4 and 9, we need to find the least common multiple of 4 and 9, which is 36. The numbers between 30 and 40 that are divisible by 4 and 9 are 36.
36 (=4*9) and its multiples.
