Answer:

70

Explanation:

You want the natural number that is 5 times another such that their sum is 84.

Fraction

If N is the natural number of interest, then it represents a fraction of the total that is ...

N/(N +N/5) = 5/6

Given the total is 84, the number of interest is ...

N = 5/6·84 = 70

The number is 70.

__

Additional comment

The other number is 70/5 = 14. Of course, 70 +14 = 84.
