Final answer:
To find the number, set up an equation. Simplify the equation to solve for the ones digit. The number is 52.
Step-by-step explanation:
To find the number, we can use algebra. Let's assume the ones digit is 'x'. According to the problem, the tens digit is two less than the ones digit, so the tens digit would be 'x - 2'.
The sum of the digits is 8, so we can write the equation as x + (x - 2) = 8.
Simplifying the equation, we have 2x - 2 = 8. Adding 2 to both sides gives us 2x = 10. Dividing by 2, We find that x = 5.
Therefore, the number is 52.
