Final answer:
To find x, when one-third of x is 55, multiply 55 by 3. The result is x equals 165.
Step-by-step explanation:
To find x when a fraction of it equals a given number, we need to set up an equation based on the cleared problem statement. The question asks to find x if 1/3 of x is 55. We express this as an equation: ⅓x = 55. To solve for x, we should multiply both sides of the equation by 3, which is the reciprocal of ⅓.
So, the equation becomes: x = 55 × 3. When we calculate this, we find: x = 165. Therefore, x equals 165.
