TEA [102]

STEP-BY-STEP EXPLANATION:

Given information:

Let x be the number

Mathematically, the statement can be translated below as

$\begin{gathered} x\text{ }\times\frac{1}{2}\text{ = }\frac{1}{3} \\ \frac{x}{2}\text{ = }\frac{1}{3} \\ \text{Cross multiply} \\ 3\times x\text{ = 2}\times1 \\ 3x\text{ = 2} \\ \text{Divide both sides by 3} \\ \frac{3x}{3}\text{ = }\frac{2}{3} \\ x\text{ = }\frac{2}{3} \end{gathered}$

The next step is to represent it on a tape diagram
