Question

one positive number is 5 times another number. the difference between the two numbers is 696, find the numbers.

Answer 1

Let the smaller one be X. The second number will be 5x. The difference is 5x-x=4x and it's 696 at the same time. 
4x=696
x=174
So, the first is 174 and another one is 174*5=870.
