The correct Answer is:
To rationalize the denominator of the expression \(\frac{2\sqrt{3}}{5}\), we follow these steps: ### Step 1: Identify the expression We start with the expression: \[ \frac{2\sqrt{3}}{5} \] ### Step 2: Multiply and divide by the denominator To rationalize the denominator, we can multiply both the numerator and the denominator by the same number. In this case, since the denominator is already a rational number (5), we can simply multiply the numerator by 5. Thus, we multiply and divide by 5: \[ \frac{2\sqrt{3}}{5} \times \frac{5}{5} \] ### Step 3: Simplify the expression Now, we perform the multiplication: \[ = \frac{2\sqrt{3} \times 5}{5 \times 5} \] \[ = \frac{10\sqrt{3}}{25} \] ### Step 4: Further simplify if possible Next, we can simplify the fraction: \[ = \frac{10\sqrt{3}}{25} = \frac{2\sqrt{3}}{5} \] ### Final Result Thus, the rationalized form of the expression is: \[ \frac{2\sqrt{3}}{5} \]
