It is a ratio of 5:13

Either 30 or 15
the # 6 and the # -5 are 30 less than their square root. 6^2 = 36 > 36 - 6 = 30 -5^2 = 25 (because a negative times a negative = a positive)
It's a multiple of 5, a multiple of 6 (since it's between twin primes), and less than 50. The only possibility is 30. To check: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30

Let x = the number Difference: 5 is less than a number: 5 < x 5 less than a number: x - 5 1234
The answer is 2. 2 goes into 30 15 times, so it is a factor of 30.
Either 30 or 15
3, 5, 7, 11, etc. are all prime numbers that are less than 30.
It is 30.
-- Every whole number that's less than 5 is a rational number less than 5. -- Every terminating decimal that's less than 5, and some that don't terminate, is a rational number less than 5. -- Every number less than 5 that you can completely write with digits is a rational number less than 5.
All of those demanding criteria are met by the number 16 .
