Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the equation 23×x=13\frac{2}{3} \times x = \frac{1}{3}.
  • Step 2: To isolate xx, we'll divide both sides by 23\frac{2}{3}.
  • Step 3: Perform the division by 23\frac{2}{3} by multiplying by its reciprocal.

Let's work through each step:

Step 1: We start with the equation 23×x=13\frac{2}{3} \times x = \frac{1}{3}.

Step 2: To solve for xx, divide both sides by 23\frac{2}{3}:

x=13÷23 x = \frac{1}{3} \div \frac{2}{3}

Step 3: Dividing by a fraction is equivalent to multiplying by the reciprocal:

x=13×32 x = \frac{1}{3} \times \frac{3}{2}

Calculate the multiplication:

x=1×33×2=36 x = \frac{1 \times 3}{3 \times 2} = \frac{3}{6}

x=12 x = \frac{1}{2}

Therefore, the solution to the problem is 12 \frac{1}{2} , which corresponds to choice .

Answer

12 \frac{1}{2}
