Let the first number be x.
The second number is 5 times less than x => x - 5
Therefore, we can write the statement as

Solving the quadratic equation:
Let us replace -5x in the equation with -4x and -x to be able to factorize.
Hence,

Hence,

Therefore, the number can be 1 or 4.
The second number can be

Therefore, the pair of numbers can be
