Answer:Let's call the number we're trying to find "x".
According to the problem, one third of x is added to one third of x, which can be written as:
1/3 x + 1/3 x = 2/3 x
We know that this equals 8, so we can set up an equation:
2/3 x = 8
To solve for x, we need to isolate it on one side of the equation. We can do this by multiplying both sides by the reciprocal of 2/3, which is 3/2:
2/3 x * 3/2 = 8 * 3/2
Simplifying:
x = 12
Therefore, the number we're looking for is 12.
