What are the two natural numbers which one of them is fifth the other, and their sum is 42?
Write an equation to represent the situation. Since the second number is one-fifth the value of the first number, we know that the first number is 5 times the value of the second number. So, let represent the first number and let represent the second number.
So, one of the numbers is 7 and the other number is , or 35.
