There are 16 numbers divisible by 3 between 1 and 50.
These numbers are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, and 48.
The reference provided clearly states that there are 16 integers between 1 and 50 that are divisible by 3, listing them all out explicitly.
We can also verify this by dividing 50 by 3 which results in 16.666... Since we are only considering whole numbers and the requirement is divisibility by 3, we should only include the whole numbers. The last integer divisible by 3 within the 1-50 range is 48 which is equal to 3 times 16. Hence, there are 16 numbers divisible by 3.
